If you like the amazing work of Ovbal Y Sego (see older post here), this is a good video about him. If you don't speak Spanish, or just want to skip to the action, you can jump to 4 minutes to watch him paint the wall below.
One absurdly talented artist, two different styles; Sego is the name used for the hyper detailed, organic style in the higher images, while Ovbal is the name used for the lower, abstract style.
