Keeping Secrets

Ah, finally the final result of something that got stuck in the corner of my files for months until I decided to finish it. And by finish it I mean practically redo the whole thing lol. I scraped everything I had minus the horse and background and made a bunch of changes to eventually come up with this. I have spent so much time on this the last many nights but still not 100% happy with it but I definitely feel like it's an improvement on previous efforts.
So, as always comments and critique are wanted so I know what I did right and what I can improve upon
