Well, here's the finished temple
I'll just go out and say what nearly everyone is thinking: it's bad. It's just bad.
The shape of the temple is just nonsense, the strokes dirt in the temple looks horrible, you've probably never bothered aobut detaililng it and it's so extremely random.
For now, keep it to 2-3 different types of trees, I suggest doing something in the same colour. Place trees down in groups with bushes, don't just randomly throw them around.
Delete, for god sake, the thrones, the ice, fire, earth and energy thingy (can't recall the name) and remove the pillars and statues and everything inside there, eh...
Work on your shape of the temple, go through 'nature' and look for interesting things you can use (I'll go ahead and say tufts, maybe?) and start putting some effort into making it.
I'm not trying to be offensive in any way, I just wanna help you D:
