Brazilian Artist Alex Senna’s Graffiti is Awesome!This stuff makes every building it's on look great! Artist Alex Senna draws brilliant people on the sides of buildings in Brazil! Sometimes he does really cool stuff with shadows… He has a clever way of making you think things are there that aren’t! Once-boring walls are transformed into really nice scenes once he’s got his hands on them! He’s been all over the world. Look how cool he made this shop in Denmark look! This one’s in South Korea! So is this one, which is HUUUUUUUUUGE! Great work, Alex!
