I think the elements that you’ve modeled are quite nice, but the composition of the scene gives it a sense of clutter, not of peaceful meditation really.
The foreground trees shouldn’t be blurry. It makes the scene seem tiny, as though you’re photographing miniatures. They wouldn’t be that out of focus with a real camera, for example.
The tree just to the right of the temple appears to be behind the temple, but its trunk appears to be in front of the temple. Almost at the other end of the bridge. Same with the orange, smaller tree just to the left of the temple.
The rocky shores could use some displacement detail, or perhaps a more interesting and dirty shader. Those rocks are nice, but I think you need a lot more of them to sell the illusion.
The background looks rather empty. There’s landscape there, but not many trees? What does it look like on its own? I’d detail it out more, with more trees and some kind of horizon. As it is now, your existing trees hide the horizon almost entirely.
Just some ideas! Keep at it, it’s coming along nicely.
