Wow great colours! Gives the picture such a different look than it was as the IDW cover.
Wow even when the artist comment is only 8 words people still don't take the time to read it ---^ Anyways, as always Greg you're better than me so there isn't really anything I can comment on that would help, and as it is that's pretty much kickass and to me looks ready for printing.
Excellent!!! Now just draw us a picture of Optimus Prime or Starscream
