looks great! i can tell you kept your light source in mind while making this, which is something a lot of skinners (myself included :/) really need to work on. if this is your first time shading a skin, this is an amazing place to start! keep at it!! you're doing great!! :)

Better than mine!

I really like how you used a light source. Just remember that there should be shadows where the arms meet the torso and the legs meet each other. I can only see one of these shadows on the front of the legs on the pants, so good job with that one. Also remember that there are folds in the clothing and the texture of the hair. Try adding those to your skin. I also agree with wolke about the cast shadows for layers. Overall, it looks ok, with the light source, but confusingly smooth.

Note that I'm not an expert and this is just my advice.

looks great! really soft, i like that. just try to keep in mind, that different layers of clothing will cast shade onto each other. the jacket for example will cast shadows on the shirt and pants. the shading for the legs is amazing tho.

Is cool!
