What a pretty place. The light coming through the glass is so unusual. You've picked it up in the sky reflections and in the sky itself. Superb. Greens and reds my be a little hot but they offer effective color contrast ... I'm not sure i'd change them much ... if at all.
This is a nice scene and the composition is well done but I am really not a fan of overprocessing. I think that if the changes to this photo were set at 50%-70% opacity over the original it would probably have been just right. Beautifully lit with nice colors without looking fake.
