I like making bafs, there fun. Last one i made was the baf wasp from the dcu baf giganta. Sculpted several things. Twisties and hot glue are his fingers, because atom smasher had fists. I left him unbuilt for a reason, because its not for me and i wanted the person who will own this to get to build it.
I think it would be cool, if, later, you can update this custom with an assembled picture, if the person who you made it for will provide one for you to use (preferably with him pounding on Xavier).
