#004 Charmander

I suggest you exaggerate Charmander's line-of-action a little more, by expanding the 'rise' of Char's hips and belly. For the latter, lower Char's belly so its outline doesn't merge anymore with the outline of Char's back-leg.

Char's right hand has a nice flow and 3D look; in comparison, the opposite arm might do with a line added in, that distinguishes the fore-arm from the upper-arm. e.g so the fore-arm 'overlaps' the rest of the limb just a bit, giving it perspective while also sharpening the elbow.

For the feet, changing the size of the claws might add more depth- or it might do the opposite! It depends on a couple things, really, like if you prefer keeping claws all the same size, or emphasising a main or 'big' toe similar to humans or dinosaurs/birds/reptiles.
