This is a quite nice idea, but there is a major problem with this picture... so to possibly make it better heres my advice:The problem is that the eye is way to distracted. You should probably try to draw the viewers eye to the cabin, but it is distracte by the huge amount of similary bright crystals. So maybe try to make them less bright and dont put them all over the image. Even though i think you already added a vignette it could be stronger and should almost remove the crystals effects on the edge. I really do see potential in this image, but right now its just to confusing.Keep learning and you will succeed
