Looks good. But I have an opinion to why it looks like ice that you may not have heard yet: the glass seems to be blue. If you'd have put a sort of grey-ish colour it probably would have looked a bit more like glass... Nevertheless... It looks quite impressive!
Not a bad start. Ice does have a texture similar to glass, but it's important that it not look completely translucent; otherwise, it takes away from water's simple opagueness. Heck, just take a look at Kyurem's official art; the ice is not completely see-through, but it nonetheless has a nice glassy appearance to it. Keep it up; I like where this design is going, and I think that the right ice texture would easily make it more than poster-worthy.
