I'm loving the mountains, especially with the contrast between background and foreground, and also just the piece in general. The style of color and strokes is very nice.
Critiques now: it looks like he's in a fenced off closing. Maybe if the left fence curved out a bit more, and you defined the road ahead a bit more. It's a bit hard to see at first.
Also,a couple of the brush strokes are a bit too large and noticeable on the middle mountain. Just more, smaller strokes would have helped with the subtlety there.
All in all, great job!

This is nice. I like how you blended the BG and added shading to the Mts. which gave it depth. Overall the shading is good, and it makes for a cool Western theme. Good stuff.

What a loyal horse it even carries him even if is probably dead. It would look nicer if there would be a castle or a town to the far north.
