Blocks and Spheres

[Someone]

I see well here is a sample, tell me what do you think about it.

Wow, the shading is really good! I'm kinda curious to know how do you do the reflective pattern. Are the lines, aren't they?

The shape, though... Albeit good, I'd imagined it less square and more long on the vertical axis. If you'll use this one as basis, I think it would be quite similar to, you know, those on The Sims? =P

I can make it Larger, around the size of a basic RTP character. I have a picture which shows how to make jewels, the reflection is the same at the crystal. I used it to look at.
Do you have a certain color in mind ?
