Thanks...I do use models for all my drawings...if I can't find one pic that serves my needs, i'll piece many together to get the desired image. I used to draw from my head a lot, but I am really picky when it comes to details...to me, the small details make or break a drawing.
I thought that might be the case. Alex Ross does the same thing, and when I saw your work I was immediately drawn in by the attention to detail. I'll be watching as long as you are drawing. Great work!
