I found what seems to be the only survivor from Brazil - a piece of watercolor paper with washes done for Behzad's workshop. I decided to try the Nun's Island view again and here is the result:
I suppose composition-wise it is not the best. The tip of the island is like that - few buildings with big spaces in between, but the fall colors looked great and this is why I stopped the other day. I guess I could have skipped the buildings...I'll keep trying, I like this idea a lot.
