If I had to choose one for you to continue with I would pick the first. As for improvements first of all is the issue with the sky, at the moment it looks like the sky is just too large; the sky and background terrain covers 2/3 of the image before you get to the detail part. I have two suggestions for fixing this, either draw in a really fantastic sky in Photoshop or lower your POV closer to the ground so that the trees can help make up some of the difference. Speaking of the trees they look a bit too uniform now, I would make the size differences between trees more dramatic, the ones behind the horses in particular. The sense of depth is really well done though, I like how you can see other towns and structures in the background, maybe a better sky could help draw attention to these? Anyway good luck, post updates soon!
