Not bad, given the limitations of Paint. Isn't Kevin's shirt black, though? Also, I pray that you don't overlook the glaring similarities between Dirt Boss and Cannonbolt.
I think you should try to make the 10 aliens (the old ones, not the new wierd ones) into TFs. That would be awesome. And nice job.
Awesome job Spidey! Right on the money with Starscream as Kevin, always thought he would be the one to match up with him....
