Reminds me of a whale...
Which is pretty cool. I like the colors you used especially.
The only thing that I can find to complain about, is the right front wing of the closest carrier. I'm not sure if it's just me, but the position of it seems a bit off, as if it's tilted downward a bit too much. Maybe that was intentional, to show that it was turning downward to steer the carrier in that direction, but it just looks very mis-placed to me.
Other than that though, this is pretty fucking awesome man. What programs do you use? If you don't mind me asking :P
