Galvatron's Plasma Bath

This is my interpretation over Galvatron being imprisoned on the desolate plasma planet Thrull. After the "Chosen One" Rodimus Prime hurled him through the hide of Unicron head-first he landed on Thrull. There Galvatron's already formidable powers are augmented, yet at a price, his sanity.
 
I tried to draw his arm protruding from the surface but that kept on annoying the hell out of me because I couldn't draw it correctly so I scrapped the idea.
