I was truly impressed by this! I think it's mostly because you get to see all of your great characters in one spot. Granted, I'm not familiar with any of these guys. They still all look wonderfully unique. It wasn't the kind of tower I was thinking of. Then again, I guess any tall structure is technically a tower.
It was great to see such different designs. You really made all of your creations unique. I think my favorite would be the one on top. Boy, that came out dirty. I hope you use these guys well!
