Nice, I think this has potential to be a really successful image. Your mark making is stellar, I'm envious. When I paint I usually attack the canvas like its on fire and I might be able to beat the image out of it!
Perhaps shifting the horizon line to be slightly lower might help. I think the character is looking over their shoulder but I can't tell. If they are that explains the way you painted the hand on the staff and now that I see the strap I see that's what you have in mind.. Nicely done though.
