Mr Putin is a Judo master, wearing a black belt.
...few days later: One friend just sent me an e-mail telling me that he FEELS DIZZY when looking at this, as with all the images when the distortion is made by some digital tool. I made this caricature drawing it the usual way when I work digitally, using my Wacom tablet, but, at the end, I wanted to see it distorted even more and used the warp tool in photoshop. This is that version, so my friend is right! Anybody else feeling dizzy watching this? I am really curious!
