This is really cool and was probably one of the most unique takes in the cover contest that I saw, because it didn't try to imitate the conventional boxart standards. It really does feel like a surreal kind of dream...(or a Mega Man in Mathemagical Land Disney Special )..., and keeping Rock uncolored helps that concept stand out. It's also fun to try and pick out all the items and characters you crammed in there.
Thanks very much Miyabi, your words are so kind. I tried as much as I could to do one of those unconventional-like covers, just to see how different from the others it'd be. But not less interesting. Glad to see that you can appreciate each and every details there!
