Birch ATC 1

After watching Dani Jones's Ustream, I was inspired to pick up gouache again. I'd bought it a few years ago, but used it rarely since I didn't have much luck with it. I tried again and drew some more little birch trees (or some long red tubes, if you prefer.)
I'm rather enjoying working with it now, so I penciled a couple more blank ATCs to try it with later.
