Thanks for all this, Serge – je te remercie beaucup! Since I know I can draw, but I've never felt self-assured to start using Photoshop outside the photography boundaries... I saw your fantastic samples of skill and I decided to improve my abilities, and to overtake my prejudices and limits.
I really enjoy your works, I assume them as a paramount. And this upside picture taught me a lot. Thanks again!
P.S. By the way: what's your interface? I mean... which kind of mouse/pen tablet would you recommend to a beginner?
