and she is Rosebell!

In this artwork, I tried to simulate a 'digital fantasy illustration' starting from 3D and using different render layers mixed with Blender Compositor (I used Photoshop only for a last touch of vignette and vibrance)

First test with Rosebell model with textures. 
I baked: 
Color, 2 AO and Normal

One of the Munpets! 
They are magical spirits (... 'pets'?) summoned by Rosebell. They change color according to mood of their 'master'.

I used a simple sphere with an emitter inside and a texture for the cross-star. 'playing' with material nodes
