Not bad, you might want to add shadows though. Try looking at reference pictures of similar poses (or if you can’t find any, try pulling the pose your self in front of a mirror) and look at where the shadows fall, then try and copy that. The standard places are beneath the chin, under the arms and on the inner leg. Also under the fringe and bandana could help as well. But for a first try at shading skin it’s pretty decent, keep it up.
