I bumped into Usugrow today down in Harajuku today, super cool guy that just happens to be one of my all time favourite illustrators. His style speaks for itself.
Its almost embarrassing to be working out of the same city as such amazing talent as Chris Wahl, a highly versatile commerical illustrator that throws down in equally in 3D, His blog has some cool walkthrough vids and you can buy some stuff here.
Strangely enough, here's another post featuring astronauts in random situations. From illustrator Raid71, his work is normally very retro folky, which i do like, but these BMX illo's are rad.
