I waited to comment on this till I could see the photographers comments. I agree that the saturation was overdone on this. But I think it would have been beautiful if you had added some softness along with the saturation.
This is a very pretty scene, but is a bit too contrasty. It looks like a very relaxing place, but the feeling of the shot is unrestful. You go from too dark to too light. Maybe play with levels a little more? I like the red tones against the blue.

The water color looks a bit unnatural, but the saturation looks pretty good on the grass and the foliage. I think toned down a little (color), this would be a great shot. -7-
Beautiful scene, with fantastic lighting. The strong diagonal created by the stream works well to draw my eye across the shot, and the arching trees add to the interest of the shot. The colors are a bit too over-saturated, however, and detract significantly from the overall effect of your shot, in my opinion. --7
