Something has happened, probably in post-processing (contrast?) which has made some strong lines - looks like broken glass over the top of your frame.
I suppose I like the photo because of the memories it brings back.
It's really tough to disassociate your experience from the actual photo you captured (I"m still trying to learn this). There are various ways to help. To take it to the extreme, I know a top landscape photographer who puts away their negs/files for 6 months before they even look at them again - to take away any connection to actually being at the place, and edit the photos dispassionately.
