Holy wow, that took a while to compile.
The first version freaking went all.... corrupted on me. .__. 
Yeah, I did this all tonight. When I should have been working on commissions, I know, I know. B-but look how productive it is!!!

I hope this helps you guys in any way at all.

Sorry I couldn't describe things in words better. Looking at the progression helps more, in my opinion, hence so many scans.

Feel free to re-draw this all you want for practice, and you can re-post as long as you credit me (and maybe link back here so others can learn, too!).

With what kind of pen do you make your outlines? ^^
Tip: Shop ebay.
I was looking for pens like that almost 2 years
