Got some critiques and revised these two drawings.
EDIT (Update):
Old drunk samurai revamped. Although, I made him a lil bit younger on this one. Played with his proportions a bit to get it looking a bit more realistic.
This is a concept I did, and will be going over for a class demo. The topic was to create something that had symbiotic features, in my case, I decided to make a new parasite. Very small guy, only two times bigger than a tick! The process I went with this was silhouette thumbnails, to basic gray scale render, to final color.
