Although I can not really say I am feeling the final product, I definitely appreciate the time spent homie.
A couple of notes:
1. it is a good idea to go from light to dark, so when outlining try to go pretty light, or else you will likely get blotches over darker areas.
2. instead of going with the black you can use a cool gre/ay (about 30%-60%) or a darker shade of the same color. Supposedly you can get a couple of shades from one marker.
Great tutorial, remember there is not a right/wrong way to render
