The first thing that occurred to me when I saw the thumbnail was that the ship was flying among pine cones. Clearly, seeing the picture at blown up size, this is not he case. I actually kind of wondered if you knew you were hinting at this, ie., the symbolic meaning of the pine cone. If not, feel free to write this comment off as weird.
I will say that you are one of the best 3d artists I've come across yet.
