It actually feels more like ice! I like how the blue colors and the reflection of the light creates that feeling. Generally, the color-scheme is really nice and the way the blue goes from dark to light is really nice. Other than that, I feel that this photo is a bit boring. I feel it needs something as a focal point. The focus is everywhere, and your eyes don't get a point to focus on and rest in the image, which is a bit of a problem. The composition is not bad, but it could have been better. Try reading on things like The Rule of Thirds.
omg I love this I love the color, the shot, the mood & literally everything about this. I think what gives it the ocean-y feel is the slow waves. & the beams of Light set this off so well. Its just a really good shot.
