heres things to improve on :
1) the moon is infront of the mountains. Put it behind the mountains. Since its a moon, you might want to replace those glows with something circular instead with little glow, Or you could just simply keep moving it behind the mountain .
2) The rocks are too small and look rather bad when reflected. Instead, use one large rock for those isalnds and reflect one large rock with an upside down version of that model.
3) everything else is pretty decent and rather creative, i especially like the link model, the reflection and the moons glimmer on the water. Also the details on the mountain are great. However, since ur using reflection, you might need to reflect all the details on the mountain near the front. Every door, light and building. Since thats too hard of a task, i suggest getting rid of the front reflection all together and make it a single landmass with the land that link is standing on.
Also you might wanna fix the moons position its off .
i hope that helped u out =) good job either way i like theglimmer alot ;D
