I've been working on a project for a year now and I wanted to share it with you all! It's Angelthesis (http://www.angelthesis.com), a site that teaches aspiring manga artists how to draw from scratch. I've written 15 lessons so far from what kind of strokes to use to how to draw face and hair, etc. I add more lessons once every 2-3 weeks (since they take a very long time to make).
I also have a reference gallery updated once a week with various poses, facial expressions, costumes, etc so that when you're stuck, you can go through the pictures and hopefully be inspired by one of them.
Lastly, I would like to invite you all to join the Angelthesis Forums (http://www.angelthesis.com/forums)
I hope you'll find all these resources helpful!
