I started doodling in high school. Simple, doodle-y things. You know. But gradually I kept making my doodles more and more detailed and intricate. Larger and more elaborate, little by little. It slowly got to the point where people were upset that I was still calling them doodles. So now I mostly call them drawings, or "art" if I'm feeling really brave, but really most of them are still doodles in my head. 

You can watch me draw a bunch of these on my YouTube channel here:

And then I plug my Instagram and my Facebook where you can see a boatload more.
