Texturing

I've chosen this design:

Having the UV layout allowed me to use exactly the same textures I used in the design. But it left seams in areas where I cut the mesh to lay the UVs. To get rid of the seams I used BodyPaint3d. It has a Clone tool which allowed me to quickly paint the seams out.

Here are few examples of the texture maps:

Above pieces are just for the shiny parts of the body. I used Blinns for them. For the fleshy bits, like the trumpet, I used subsurface scattering. I wanted them to look soft.

The wings are transparent Blinn with a rainbow texture applied to the specularity.
