Ooooooh, that scowl on Perceptor's face... ! This piece is just oozing with his heavy-duty bad-assery, with heavy-duty weapon included! Hard to believe that he was a scientist.
I love the texture you used in this piece, as well as such striking detail, down to the highlights and the shading. This is beautiful work, everything about it! One of the most splendid pieces of Transformers fan art I've ever seen.
