Here it is! Part 2. I had a bit of trouble explaining alot of stuff correctly, but I hope I get the point across decently enough. If you're still having trouble, just comment with your questions and stuff below. ^^ I'll try my best to help you.
It's very helpful. ... At least it would be "very" if I used MS Paint x'D But since I bought my Drawing tablet, I changed to Paint Tool Sai. No curves needed. I just change the size of the paint and voilà!
I did try it like this, but with my version of paint I didn't get anywhere... So I went back to my old tyechnic of sketching the mane out in a bright colour and then going over it with a thick curve tool in the colour I want the outline of the mane to be... Then I would remove the sketch lines.
