The glow is from a tiny LED signifying it's wireless. It adds some needed light values to balance out the midtones and darks. In hindsight, I wish I had kept it a lil more subtle.

I see what you're saying about the hand, I never did really retouch that up. The problem isn't so much that it's to small, but rather the fact I did not properly show that is was angled. The wrist is bent slightly forward so the knuckles aresomewhat facing toward the camera, unlike with the other hand which is flat to the camera. There's almost always something I miss fixing in pieces like this - the ones I end up starting and stopping a bunch.

Thanks btw! I'll be keeping this in mind for the next painting.
