Eh, the turret may be a bit unrealisic, but I thought it looks more futuristic, and I couldn't find a way to do the viewports in a way that satisfied me unless I could do assymetry, which I have yet to delve into. :/

Nice work on the hull shape, but the turret is unrealistic and I see not viewing ports for the crew and many of them don't have hatches.
