It already looks clean and no maintenance. What vision do you have?

I see colorful pots at the end to enhance & add to Buddha focal point. Don’t know where you are - maybe instead of colorful pots place Bonsai red maples on either side of him? Add a round ceramic garden stool, or two in front for color? The gravel path I’d leave as is with all emphasis at end.

This is a cool space with a lot of possibilities. I think the Buddha is too small to be a focal point, however. How about three colorful planters with the middle one being larger and taller? Plant showy specimens, including something that spills over the side of the planters.
