I really like this mold. The alt mode is interesting, and the bot mode looks powerful and imposing....with one exception: the tiny arm. I added Movie1 Leader Meagatrons hand to the arm, and added a small piece of armor, and it seemed to make the proportions work a little better. After painting him up, I noticed how the backpack reminded me of a turtle shell....now I need to pick up another one so I can do Snaptrap!
Funny, I'll be posting mine tonight. Though love your idea for the arm. Now I gotta buy another to do that for myself. And as for your snaptrap, you get the coolest ideas. Mac
