The bright green is obnoxious, and unrealistic. I think the overall terrain needs some work, like instead of just plain, horizontal, and reverts to slope with no transition is a little corky. I like where it's heading, though. I think when it's all said and done, it'll look really good. Try to spend a LOT of time on the shrine itself though. That'll take attention, and make people pay more attention to that, instead of the terrain.
Keep working on it.
