I really liked this cover Alex did
The original colors were kinda stale and I had some hardcore conflicting light values going on between the foreground and the background, but Denji Tippu(my goal is to slowly irritate the hell out of Denton J. Tipton with irritating nicknames) brought it to my attention and it was fixed. Alex wanted Megatron to be glowing- like evil is causing him to go all rage on Optimus.
(another artist stepped in to help with this one, but I forget his name! John-something, I think? Sorry, I just color pages
