A current favourite artist is 'Linn Olofsdotter' who focusses on illustration. She's worked for a number of clients such as Starbucks, Levi's, BIK BOK, Computer Arts and loads more. Her combination of illustration with lots of different textures and colours takes them to a deeper and more interesting level. She inspires you want to pick up a pen or a paintbrush and be really creative. It's really great to see a combination of hand drawn & scanned images looking so professional.
