the first and third one are good imo. first is simple but yet good, it got all the details it needs tho its autobordered there could be more stonelike addons but yet its just crude version still it loos lie there is everything you need for low-medium mapping.
third pic is very good, it looks like been made with idea unlike the middle one, there is everything tho i dont like the way you put trees in there, every doadd is on its place, stones, grass tuff, dirt or flowers they look good, all that would need to readjust are trees.
Yet i find some uniquity in middle pic, i like the white sand details in it, there is also border missing near the stairs where grass connects with mountain ground, looks less ab'd but it still is neverethless all three parts got something good in them, why not mixing them all in one? like adding white sand border inside the entrance in 3rd picture and removing some of trees
