The colour gradation is smooth throughout, which shows that this photo has not been over-processed (a common digital post-processing fault)
The tight crop doesn't sit well with me though, and the spread and variation of colour prevents this image from communicating anything concrete to me.
A bit later with a full red sky, or a bit earlier with a full blue sky may have carried over a comprehensive message.
Woah, I love the sky in the background! The tilted tree filling up the whole frame is great too. I'm trying to think of something wrong with this image, but I can't really think of anything. I like it
