Drawing

I haven't drawn anything for about three years. After I graduated school and couldn't find work in animation, along with other issues, I lost my passion for drawing. I just started taking some graphic design classes and last weekend I found that passion again. I was watching my Season two DVD of Buffy. I loved School Hard since that episode introduced Spike and Dru, my favorite characters. So, after capturing the scene I did this sketch. I think I might turn it into a charcoal. If anyone sees this please let me know what you think. Am I even close or way off. Like I said, this is just a first sketch, and I'd appreciate any constructive criticism. Thanks,

Angela
