Everything is near perfect actually,

Those waterfalls just ruin the whole level I'm afraid. Make them all single lined ones (get the center tiles and just stack them) and dont even make them go over that cavern, it doesn't look right. Fix the river so that it goes to the waterfalls. Yeah, those waterfalls are like -5 points. And waterfalls go on the dark dark water (dark blue).

Light Effects can be your friend. Use them on the lanterns and on the bottom of the waterfalls (see Graal2001's waterfalls)

And take the moon out. Or you could make the level to be at night. I've never seen a moon reflect in daylight.
