Waterfalls

My lovely girlfriend and I have been hiking a lot of waterfalls this summer--thank you Keen. At the base of one of the falls there wasn't a person in sight so she laid on a rock to nap and I attempted to sketch running water. It wasn't a bad attempt considering I haven't done it before and there is no white watercolor. I have a hard time leaving whites, so I had to pencil them in so I wouldn't blaze over them!
