A really nice piece with interesting thought behind it, a bounty hunter finding his treasure in the lost ruins - sounds cool to me! Also blurring the character attracts the attention to the axe, that's a really neat trick, altho you might have used too strong blur, You will learn to balance it real quick ^^
I think that some stronger light / darks contrast would really make this piece pop. Making a new layer that would be really dark grayish-blue and making it just a bit transparet, then adding some strong blue light on the axe and front of the face would make it really great :D
You are on a really good way to improvement, keep it up and You're gonna go far! Good luck!
