That's very good. I miss my G1 Grimlock, gave him to a friend 15 years ago and he never gave him back. Would happily buy a reissue if one ever happened. Hoping to get Masterpiece Grimlock soon, already got a picture in mind for him.
specially because he is in his both modes like I love to draw all the Transformers (if you saw my gallery is full of them XDDD) and that's remembers me XD that someone asked me long time ago to do Grimlock like that but I never done it and I don't know why
