This started out as a general sketch of a super robot body type that i did for practice and reference. i kept adding on to it and eventualy decided it looked enough like optumus prime that i might as well turn it into that. This is my personal rendition of the iconic character. Due to the high res nature of this image, it got to a point where i could no longer add on to the image without severely slowing down the program. I did intend on adding the light reflections coming from the axe onto the rest of the body but I literally can't. I am however pretty pleased with what i did here.
