Optimus Prime (Leader Class)

Leon mentioned to me that the Leader Class Optimus Prime is one of the toughest he encountered so far. Not only are the parts small, most of them can't be airbrushed. So more hand painting is required. The flames on the truck is another killer. I have seen others who simply sprayed a top coat over it. Here, he specially scratched a weapon from some gundam parts. What do you say?
