Book Cover redo

This is a redo of the old pic: [link]

I mashed together a bunch of pictures and it took forever. I've never really done any photo editing before so critiques and suggestions are very welcome!
This is still a work-in-progress so you might see something similar later

I used these stock images:
mountain: [link]
sky: [link]
castle(it's up there between the arms): [link]
Tattoo&flowers: me
Hand models: kristin and me

Edit:
I don't know what happened to the edges of the picture-I'll fix that later

Edit x2:
Here is the link to the friend who's story this is for: [link]
