Although I'm used to the glassic G1 designs, but this is really well done, he looks more alive in this shot then the classic design. Great work, I hope you persue a career in animation you'd be great at it.
The decepticons look awesome, Megatron looks like Super Megatron (from Battlestars) and Movie Megatron got smooshed together in a good way.
Starscream is great, and his alt mode is Cyclonus like.
Blitzwing is, well awesomeness incarnate.
