I think it's #3. This one had me scratching my head, but I can't complain. A cover's a cover. I was also happy to be able to do a Devil Dinosaur and Moon Boy. Cool! Skaar, Savage Land, Kazar, Devil Dinosaur..Kid Colt? Alright, why not.
This looks great! I love your lines. I super love the composition too! However, the placement of the pterodactyls is kinda weird to me. They go right to the smoke, which kinda draws my eyes there, perhaps maybe the should point to Kid Colts chest...maybe? I don't know, that's grumbling with a gun to my head, all in all, this is A+ work my friend! :} We gotta get you in animation somehow!
