hey, I dunno what to say. your light reflects are awesome, implus, you have a smiley in your light source. So all in all I want to say koodos. and even give you a brownie. However, you are missing intencity in your light. The furthest away you are from the light source, the dimmer the light.
Because of this, the light on the hand should be brighter than the light on the chest. I see you did this within the chest, however, I would brighten up the hand even more and it will look good. Normally the lightsource is so bright that there are hardly any lines visible in the hand... This is so since the hand has ambient light (I think that's what it's called) meaning the light source is everywhere on the hand rather than in one direction.
Also, the foot is the same thing, the distance...
hope that helps
