I've been going around as a writer, but started getting drawn into Concept Art and 3D modeling. I'm currently finishing my studies as a 3D artist and will then be let loose on the world. Beware!
I might have some work to do on better shading, but I'm quite happy with the result at first glance. The model has 428 triangles. I guess I could save some, if I simply paint on the diamond or put it on a simpler sphere.
The one with the grey background is the render from XSI - without shadows.
