Zaggy, perhaps you can improve the leg without further uv-editing:
Cut the triangles/Faces with knife, shift+k, then perhaps "exactline" or "midpoints". Then scale that around or make mor of that cuttet-rings.
hehe, you mustnt go back that much for cruel handpainting jobs. If you ever have hered of a game named "clonk". I made some objects for it some time ago but really cruel was making a new unit because you have to draw a set of maybe 40-pictures which show the unit walking, punshing, throwing... I think these pictures had around 9 pixels for the head so not the same but still something that could have lead to similar feelings
you can join tris to quads with alt+j and split by strg+t, but you may know
