Detail, color, exposure, whitebalance, all the technical aspects of the shot are there.

The only issue I have is composition. I am not exactly sure if there is a crop that maximizes this shot, and I dont know what options you had for shooting this (IE: how far you could have hiked back on the left hand side of the shot to get a better and more balanced perspective further down the canyon.)

All in all, it looks like a beautiful spot worthy of a longer visit (with some very protective hiking boots and long pants)
