Interesting style, reminds me of alot of my old stuff. And personally, I don't think all of the ice should be reflective like that. Reminds me of some sort of blue mirror structure. I think some translucent and distortive parts with gentle color reflection and strong white highlights. I also think the shape of the ice might look nice a little more rugged, but still some of that crystalline look you've got going. And I'd like to see some frosty freezer burn, too, think it'd have a nice effect.
As far as the elephant goes, I like the shape, but I think with the shading and some of the lighting you've tried to keep it strict to the lines you have drawn around it, which makes displeasing patterns to the eye. Be more free with your shading shapes, use it to define interior form and texture rather than to reinforce the original lines.
If you need an edit example I can make it happen by tomorrow.
