Thank you everyone.
The last one was a challenge. I'm sure lots of folks here have looked at heavily wooded areas thinking "someday I'll try that". Well that's this summer for me. It's very easy, I admit, to get lost painting shadows, trees, reflections, etc, etc. I thought it would be easier painting small ones first.
This area is beautiful with trees that have massive root systems anchoring them into the banks of the river. I plan to visit there again in the fall and winter, (after mosquito season) because I think the root systems of the trees will make a great complex study and that will keep me preoccupied during rainy days for awhile at least.
