I really like the photograph, and given the conditions, and what you were shooting with, I don't know what more could have been expected. Overcast days (my preference too) usually don't yield bright blue skies, if I may be so bold as to state the obvious. All I noticed (again, if I may be so bold) is that the rich contrast of the waterfall was not matched by the trees and sky. That may not matter to some, but for some reason, it caught my eye from the start. That's why God gave us Photoshop. I enhanced the upper portion, especially where the trees meet the sky (thanks to the "multiply" layer option). Not a BIG difference, but just enough for me. That's all. Like I said, nice shot Michelle.
