Hey man, great stuff in here. Looks like you are working hard on your skills, I need to do more studies like these.
You mentioned in EOW-49 that you are trying to get better at painting:- your lineart is pretty strong, and this (for me anyway) is the construction/foundation for your painting. Put your lineart on multiply layer, and keep it there, painting on a layer underneath until the painting almost works (values & colours). Then flatten it down and start painting over a bit.
This is obvoiulsy not an easy thing to explain in a few lines of text - if you would like any help just PM me, I hope you see this as positive and not patronising.
I never thanked your for the way you described my EOW these words you used , I had to google them you know them, but wow man thanks. This type of encouragement makes me want to try harder.
