Heh, one of the good things that Retooled is good for.
It does look nice, however I'd add teeth to the higher part of the mouth, almost looks like he has 4 eyes, as well as moving the chest part a bit up.
I know about the original Mr Bones, however this reminds me of Obwalden Overlord now. Is the chassis unchanged from the original as well?
I swear, did AS swap the axle/motor weight? Axles are so unstable. Might want to try a different heavier servo.
Don't know if Retooled has small enough servos, but what if the arms would actually be rotateable?
