Generally I like it. My one issue with it is that such a large percentage of the volume and I assume mass of the ship seems to be devoted to non-cargo/crew space. It being a container transport makes me think that the containers are the only part that will be holding cargo and it looks like they take up maybe half the total volume of the ship, that just doesn't seem right...
I mean I really do think it is a gorgeous ship, I just think the size of the cargo area compared to the rest of the ship is terribly unrealistic (and yes I know, space ship computer game, but still).
I think you could keep the design if you made the containers larger in diameter and perhaps shrank the fore section a little and do something about that dorsal ridge, of which the purpose I cannot fathom. Either shrink it and lose the windows or lob it off all together IMHO.
