With people, the first thing you should do imo, is get your proportions worked out ^_^ Decide whether you want to draw a tall person, a child whatevs and the proportions change accordingly. There is a head-body ratio but I can't seem to find it right now...
Sure thing ^^ Let me know if you have any specific problems and I'll do what I can to help :)
The avi? Yeah, I can't stop lookin at her either XD She can see into your SOUL....
Really? Omg, she's so cute! But does she really have pink hair? XD No new drawings, but there will be soon, I hope. I'll show you if I come up with anything ^^
