Gah don't look at this, it's awful, lol. I still am not very happy with how I paint rocks (at all) but
and I decided to do a tutorial swap, so I can learn how to draw grass. I think I'm getting the better deal.
This is how I paint rocks. There are better tutorials on DA, so go look those up, there are a few very excellent ones floating about!
To kill two birds with one stone, so to speak, this is also an art trade in progress. <3
