I can almost feel the high altitude. I was so curious to know where this was! Torres del Paine National Park -- gorgeous. Reportedly iconic towers, but I don't think I'd ever seen a photograph of them before.
Now this must have been an impressive sight to see live. Those sweeping mountains are majestic. The photo is good but it needs some touch up work to make it shine. The contrast are a bit flat in the photo as it now stands. I think if you up the contrast and played with levels and curves to get a more dynamic contrast between the light and shadows you will see a dramatic improvement in the depth and detail. Also I think that this would be more stunning in B&W especially if you get some dramatic contrasts between highlights and shadows.
