Prime Wheeljack works surprising well as a G1 Megatron Homage. It looks like a black and white image though. He could really use some red highlights, especially in robot mode. Not so much on the car unless you want to paint his windows red. Not a lot of red just under his chest and his lower arms/legs. (Not entirely of course, just the parts that don't show up in vehicle mode.) It would really help make him look less dull than just the plane black and shiny silver. I do really like the effect of the black fading into the silver on the vehicle mode and it helps make the robot mode look a lot better too, just needs that little bit of color. What do you do with the arm cannon in vehicle mode? This certainly makes a better Megatron is a car than Cybertron Megatron.
