is that cg? looks like it...
It is. CG images have got better in recent years, but they still have that too smooth look to them
Most people who do CG for artwork like this don't bother with full 3DCG production (textures, mipmaps, etc. The stuff you find in high end 3D games); the most you'll get is lighting and flat shading (like this pic...Though I can still see some color banding...Mostly in the white/lighter areas.)
