I'll work on the brightness/contrast/hue as others have suggested, but not shadows. It's ice, it has enough shadows. Since light both passes through and reflects off of ice, it wouldn't make as much sense to shade this as though it were a hunk of rock, with one side dark. The handle, however, does have a dark side.
If you'd bothered to read the rest of that post, you'd see that I was saying I would update it as soon as I got to a computer with photoshop installed, and that I had currently been working with Paint, which isn't capable of making full-scale brightness/contrast changes.
