Here's my current ice cube in the game, a little messy looking:

No animation, just a static image. Needs to be transparent so the background shows through a bit. No shadows or outlines, I'll add those later.
I'd like to keep it slightly blueish, but a more realistic color (white/silver?) would be fine if it looked good. Style should be more cartoonish, than realistic.

Please render or draw it very large, I'll resample on my end to the size I need. Please keep the view perspective the same.

Reply here, or pm me with previews and price. Thanks.
