How 'bout something like this? I think the original mesh comes from scifi meshes.

eww no!.....
the nacelles are interesting, but all the extra unk at the bottom has to o... it looks like a neat little ship is being weighed down by it, their may be a lack of gravity in space but it ust doesn't look right...
and the impulse engines are to big, at least the enineering ones are, I mean come on....
also, again, it doesn't say Enterprise, I think the nacells should be swept up towards the top, like the Connie, but it's not a requirement, look at the C and the D...... and the NX for that matter...
but for those of you who are saying it should be radically different, I disgree, it doesn't have to, it makes since that it would be, but let us not forget that the D was destroyed prematurely, with many many yeas left if she had managed to survive, and the E has had a couple close calls already, so time really doesn't have any bearing on deisgn, I mean, ttake nemisis for example, the front half of the sauce was destroyed, I thought that was it for the E, I really did, I thought "the next we see enterprise, it will be 1701-F" and ust how they where able to salvage her and not the D in Genrations is beyond me... the only conclusion is Plot , because they knew they'd need a sleaker "hot rod" ship to bring in new fans...... and they haven't really found a way to improve upon that look, so we still have the Sovy...
I think they actaully hurt themselves with the Sovy, because while I love the design, I think it was too soon for it, we needed a nice transition design, somthing like the Perception,Legacy or Arogant classes... but we didn't get it and now they are at a standstill... because the E was such a leap in design... it's hard to say where we go from here, or how to make a ship look more advanced and sleeker than the Sovy, and it seems we cant, we can come close but nothing has been done, at least IMO, that says "this is the next step" nothing that says "I'm more advanced" or "i'm faster" nothing that has anything so special about it to be the next leap....
so now they've hit a barrier, and untill something radical, something completely different yet aesthetically pleasing, comes along, we are stuck with Sovy lookin ships, it seems they will be the same principal but bigger and badder... the next step could be biological ships, an interesting idea, however, this has to be done carefully or we end up with the J, and it's FUGLY

I'm not even sure a biological texture would look good one fed ship.... let alone keep it lookin remotly human, I suppose at some point in the future our designs would seem so differen't so alien compared to the concepts we have today but I think it's to soon the really et that working in Trek, we need a transition, and for the E-F to be completely or mostly biological is just to soon, and yet theres no decent ideas on how to improve what the E brins, for a next en ship, it looks to advanced, as different as the A is to the C, maybe even from the A to the D, .... and it's hard to say whats next...
also, I thing the E should have been larger because this doesn't help the case.... every Enterpise expect the original to the A has been larger, A to B, B to C, C to D, but... the E is on;t slightly longer than the D, and its overall volume is much less, like what, half?
and they fit allot of things in the E, it has more weapons than most ships twice it's size... thanks to starfleets new militaristic aproach (but hey... it makes for a cool ship

obviously designed more for battle than the D, while still having scientific facilities, they aren't (of course they can't be, not as much room) as lavish as the D's, equipement is probably more sophisticated but there ust aren't as many resources for scientific study.... allthough somehow I doubt the D has ever used all her facilites at once, and the Intrepid does very well for limited room....

but as more a big, deep space exlplorer with scientific facilities for any occassion... the Sovy is not.... she is well adapt for scientific missions, especially compared to other cultures, however, with the mission of exploring strane new worlds and civilizations, the Sovy is more of a battleship than an explorer, even though she can do both....
but surely an explorer should have fore facilities, especially if she is exploring an area with few allied ships and bases able to do what she cant...
also, do to the hostile situations and lack of interier room, you don't see families like on the D, .....
right now, with the way things are, the Sovy is a great ship, but when things cool off and starfleet can start to explore more often, as it used to, when combat is less imperative, we will see the need for a larger ship, maybe even the size of a D'derix or still larger once they start incorporating Quantum Slipstream Drives or some other Transwarp tech that will call for more indepedant deep see explorers, that can fend for themselfs and manage without starbases....
and what will happen? they will need a larer ship, and not knowing where to o, it will be a "super Sovy" you ust watch, the pylons may be a bit differen't with a gradual curve ( I prefer the current ones though) the saucer may be widened just slightly, as icorpotate a larger pressense, like they did with the D, but no way as much extent as the D had... and you will probably see a secondary reflector and hey, if they can make it look decent, conceal the extra nacelles, they may make the saucer section warp capable, and another warp core for it, would be needed for a ship that size anyway, but I'm telling you, the overall design will be the same.......
