Your largest stone is too upright imo, can you place it so it is leaning more? Also, I think you would benefit from additional small rock in the left formation, probably in front of the other two. Also, mounding your substrate more around the rocks might help the transition from "ground" to "mountain" look more natural.
Not a big fan of the path, at least as is right now, it distracts and does not feel proportionally sized correctly.
You have some interesting rocks, keep playing around with them and you will find something you like.
