Dark of the Moon Shockwave
This is a representation of how Shockwave actually looked in the movie.
I used a movie 1 Voyager Megatron, ROTF The Fallen, DOTM Shockwave and several parts from other transformers.
I added the spikes on his feet, made the legs bulkier with some random parts here and there, his abs/chest section is also packed with new parts everywhere, and his shoulders were resculpted for that armored look.
His right arm/cannon is also larger now, with lots of parts added.
His eye and cannon light up, with a red and blue-purplish LED's.
The paint job was accomplished using several coats and hues of silver, black, gold, copper and a little bit of purple in some key parts (very, very subtle, just like the movie version)
He's also super articulated now :)
