I'm liking it so far, the second pic is easier to see too.

It does kind of remind me of a cross between an orion and a deimos kinda.
I would say that you have too many plain extrusions. El'classic box art, yeah.
Try and change the overall shape of sections rather than just extruding and beveling.

Cut corners off, warp the boxes to make 'em bent shapes etc.
If you get stuck, think of features that you've seen on other designs that you liked the idea of. Try and go with original ones too, mainstream stuff gets boring IMO.
Though its looking good so far for a first ship.
