Riverbank watercolor

This is the first watercolor I've done in a while, so I felt a bit rusty, sitting there on a folding chair at the river's edge. I think, if I were to try it again, I'd emphasize the dramatic diagonals of those big trees sweeping in from the upper left; and I'd add a kid floating in from screen right on an innertube for scale and human interest. I don't know. Maybe it's ok as is...
