Great drawing it has come out fantastic! You are making me gealous now. I must try to find the time to some artwork again....I miss drawing and painting
I'm so sorry, i totally missed your question.
Yes, I also draw chameleons (I'm working on one now, actually).
It's just B&W for now. I haven't found a color medium yet that I really like, but I'm working on it, so in the future color will definitely be an option.
