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 .

Maintained well organized hierarchy and naming throughout the outliner and hyper-shade.

Textures / source images haven't been used,
Used only Maya shaders with the colors shown in the renders.
Only keyboard geometry has unwrapped UV 's n textures.
used PNG texture of 2048 X 2048 resolution in color channel.

Constructed from the photographs collected from internet.

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

Make sure mental-ray plugin loaded from plugin-manager settings in Maya , then simply open the scene file and proceed for rendering for the quality promised in the presentation page.

Hope U like it.
