the dress's shading is still weird. define a lightsource and shade based on where the light is hitting, don't just shade the outsides.
Well, the lightsource is intended to be to the left, but the dress is a very awkward shape. I guess trying to shade the shape in and shade the lightsource at the same time didn't work out too well.
Did some work on the shading, tried to make the lighting from the left stand out more. See what you think.
