Looks good! In all the models of NCC-1701, I always wondered why they didn't have a rear firing torpedo by at the same level on the neck (or close) to the forward firing bays. You could have the same crew man both bays or at least make it easier since they would be so close together.
In "Ships of the Starfleet Vol. 1" by Mastercom Data Center, they came up with the America
class Heavy Cruiser that addressed this very thing.
