First off, I'm glad you like it, MysteryMeat and that's not too far from his personality, actually (although I'm have no idea who Sha'ly'gth is lmao).
I totally agree with what you're saying, eishiya, but Im not sure how to go through with that ^^'
I could imagine, making him turn more to the side like in the drawing and make his eyes less focused on one point. As for the other slight differences in symmtery, I wonder how to make them stand out that way in such a small scale.
