That's a very nice 'skin' you've made there.
She reminds me, in a good way, of the profile of the Excelsior class starship, especially with that nice solid, beefy neck. Very large, powerful looking thrusters spaced around the hull make me think she can run rings around bigger ships.
The forked nature of the secondary hull towards the nether end of the ship is quite pleasing, though it contrasts with the rest of the hull just a tiny bit to my eye for a reason which I cannot clearly define as yet. Perhaps as the design progresses it will disappear as an issue.
The Bridge actually is rather reminiscent of Star Trek Onlines basic bridge designs, though none of them have this precise layout. This is a far more evolved version, though, which much better flavor.
I think this design needs a tiny bit of... Clutter, for want of a better word. A rail or two, or perhaps a table along the lines of what we saw on the NX-01 or the original Defiant might work, but the way its laid out that'd be tricky even if you think the idea is worth beans.
