This is going to be a movie-verse style Rodimus Prime. I'm just having a hard time trying to figure out a base head mold. I'm sure anything will need some heavy sculpting, but I'd love some suggestions. Thanks in advance. Edit: Added sketches of preliminary work. Using the '07 Movie Voyager Optimus mold as the base. Going to trim down the front semi part and add the spoiler and to the top of the cab area. Edit 2: Added the Sideswipe head sketch. I think that really works.
