I'd have to agree with several below- the beginning and the point after 2:20 is far improved from the middle. I know it's easy to go in strange directions when the muse hits you, but scoring is all about being able to find the balance between you and the requirements of the image (or game level or movie scene) you are working with.
The trick I always use when scoring to a picture is to play through the WIP I have while looking at the picture. If it "clicks" in my mind as revealing something about the image, it's good. If the image itself seems to move or waver with your music, you did a frelling brilliant job, congrats. In this regrettably, it clicked at the start and at the end, but that's about it.
Instruments are interesting and varied, but not all are really needed or applicable to the subject matter. As I said in a previous review, think about each instrument like a color on an artist's color palette for a painting. In some cases, you might use yellow, in others, you might not. Examine the colors the artist uses and try to find tonal equals. In orchestral terms, it might be cellos = blue water, glockenspiel = green crystals, brass = black darkness, violins = white light. For electronic, the timbres of each instrument you use would similarly have a chromatic equivalent. Symbolism goes far beyond the feel of the track and also applies to your choices in instruments. :)
FD had a good point in terms of composition and form. Think about the image you chose- it's pretty static in the state it is. You're looking at a cave with crystals and water... it's probably been this way centuries and will be this way for centuries. This means your song should try to reflect attribute this symbolically. Think about the best way you can really describe the essence of this long, dark solitude that the crystals go through, the contrast of the light on the dark walls, the cold, icy reach of the water across the hard granite basin. It's an interesting choice you made, but in terms of the contest, an ineffective one I believe.
Production is pretty good. I thought the glass breaking might have been a bit too loud, but hey, it's glass breaking, it's pretty f'ing loud when it happens.
Keep compos(ed/ing)!
