Hiya! Sorry for the wait, this is such a cool piece!! I think your line quality is already very strong, the only tweaks I made were warp the wheels so they are slightly rounder at the corners of the ellipse, and I moved the features of the face of the tiger a little bit further to fit the curve and angle of the head (one eye a little bit lower and the other further into the socket of the skull) hope it helps! c: | Artwod Feedback
