I have included light setup in the scene file.

This has been modeled with good production standards.
This model was constructed with utmost care and attention to detail, with clean edge flow for rigging / facial comfort.

Model file contains inner mouth geometry also.
textures / source-images haven't been used.
Used only Maya shaders with the colors shown in the renders.

Constructed from the self designed concept drawing.

Only Maya format contains the shaders and lit setup used for rendering.other formats provides only model geometry.

Doesn't require any third party plugins, simply open and proceed for rendering for the quality promised in the presentation page.

Hope U like it.
