Okay, so I haven't given any C or C here yet, so here I go:
Overall, I'm probably going to treat this Enterprise as a while different animal, and not place too much emphasis on what came before.
In many ways, this is a reboot, plain and simple: an alternate universe, and you shouldn't be afraid to test out new ideas, because of this.
I don't like the rather short engineering hull. I prefer longer engineering hulls, such as on the original, or on the E-E, but that is okay, because this is your baby, not mine.
The engineering hull however as some nice curves, such as the tail end of the sides of the fantail's landing pad, and the cut-out for the nav deflector, which seems to recall the shape a little of the Excelsior class, Probert's Ambassador class, and the Galaxy class, but the curve from top to bottom is much longer, not as long as the Sovereign class, and not the same, but long in a different kind of fashion.
And about the forward torpedo tubes:
You could go with both options, and give the Enterprise a torpedo tube ratio of 2/1, with 2 forward for each aft torpedo tube.
I've always liked the idea of treating the torpedo launchers like the main guns on a warship, and the Enterprise's torpedo tubes could be similar to the number of main guns that Heavy Cruisers have carried in the past, if you want to go there.
If you just want to go with an even number fore/aft, then I think you should just go with putting them in the same area as the original: in the ventral raised area.
If you want to go complex, I've had this idea of the torpedo tubes being in what is essentially a turret, and the part of the raised area they are in rotating to track targets better.
