Turning the saturation down on all the bright green might help a bit, it's a bit fluorescent, but that's up to you, I like the cave feeling you created (also, a HI RES image is helpful so people can see the detail of your work)

Good LUCK!!

I turned the saturation down a bit - thanx for the comment and the advice

Very cool, I like the colors and the idea, but the candles seem huge ...

The perspective of the stone lion heads is off, since the image is from above, to see the lion heads in profile means they are all tilted at an angle, on both sides of the pool...Looks strange.

The candles are also way too large for the image, unless the pool is only a couple of feet in width.

Nix the candles. They're at the wrong angle anyway. Ditto about the lion heads.

suggestions:
1) add a little darker to the top of the lions as they are under the shade
2) add a little reflection in the water
3) instead of candles, change to fire
4) have water spray out of the stone lions' mouths
5) look at the light source and adjust overall shadows n highlights
