Two years ago, I created a tumblr where I posted an artist that inspired me every single day for the entire year. I highly recommend this to increase your knowledge of both what is out there, and what inspires you. I find too many students only know a handful of currently working artists, and those are the only sources they have for ideas. You should have HUNDREDS of artists you admire, because it will help you be a better, more well rounded creator in your craft!
