I hope that I am not overstepping a line here, as I am still struggling at my beginner painting steps myself, commenting someone with clearly so much more experience and skill. If I do, please tell me and I will shut up.
I really love the bust so far, the worn leather looks great, the wood as well. I love what you have done with the watch, it looks nearly real.
Some of the highlights of the skin can not keep up yet though. I don't know if it is the lighting on pictures, but the area at the base of the thumb looks a bit chalky. Also the highlights on the fingers seem a bit too bright or too abrupt.
To me, it feels that the little highlights in the lower corners of the mouth are a bit too
bright much. I mean no disrespect, but the first thought that popped into my head was "Hey, vampire fangs".
I've tried to come up with a quick animated GIF:
Don't get me wrong, I really love the bust!
