Jason; I would for sure bring it with you, it looks really great especially if you finish out the base like Marc reccomended. I use something called paperclay instead of putty mainly because it is cheap, dries rock hard, is very lite weight and super easy to work with. I get it at Hobby Lobby. I wouldn't worry about how long you have painted just how much you enjoy it, judging from the looks of this figure you are having a really good time. I hope to see him in Tulsa come June. Keep up the good work!
