Starting a personal SketchBook: Critiques welcome

Soki_g

I finally decided a want to start a type of sketchbook and be more consistent with my work. I think this is a good idea to keep me from procrastinating. I'm going to try to post reguraly. 
And since i really need to improve ( expecialy anatomy wise ), feel free to coment and give critiques It helps alot.
This is the latest project I've been working on:
