Was this a RAW image? If so, I'd like to see the RAW file. This seems to be a bit over saturated. The blue sky gives it away, it just looks unnatural which leads me to believe the greens are also way unnatural. Also, lacks some sharpness. Nice composition.
The original is ridiculously different. I didn't want it to look realistic per say-hence the name Oasis-just a 'perfect' place. Original=nice forest, not particularly pleasing to the eye though.
