This is a very cool concept, I specially like the sword and what I assume is a button shield/guard, very clever.
The light beam and overall background is very good at making your character stand out, great job.
What you could improve is the runes on the obelisk. What I would do is increase the size of each rune, increase the space between them, and arrange them 1 by 1 in a vertical stack...
Also I didn't get what the silver thing behind his hat was supposed to be.
Last nitpick, the right leg sits on top of that small patch of grass' fill layer, just letting you know, but it could also be a choice...
Anyway, hope this helps you and again, nice job!
