Sorry to go against the grain but I don't like the second scape anywhere near as much as the first. Having said that I LOVE the RHS of this second scape I think if you can have the LHS of #1 and the RHS of #2 you will have a beautiful layout.
I just think the LHS of this is flat and lacking. It tends to look like a separate layout because the orientation of the rocks is horizontal whereas the RHS is vertical.
Besides that when you plant you will loose so much rock.
I'm scaping a tank at the moment and I was pointed in the larger rock direction and it improved the tank no end. I reckon that you should at least try it. Take plenty of photos of this so you can go back to it if you change your mind.
But I think it's looking good mate.
