Once happy with the Photoshop work I moved on and adjust the seams. The texture's seams were created by the edges where the UVs were cut during the mapping process and I used Maya 3D Paint tool to correct them, using especially the clone tool. I finally back in Photoshop to create the other maps: specular, bump and diffuse. I used a Blinn shader for the body, a Phong for the eyeballs and a Blinn for the teeth.
Posing the Tiger
I decided to go for a pretty classic pose, with the tiger lying on the rocks. In order to do that I first created a rock starting from a polygonal plane making it pretty dense, and sculpting it using the sculpting tool to achieve the desired shape. I made a UV projection and applied a texture created from my photos. For the background I used a simple plane with part of the same texture applied.
I build a simple rig for posing the tiger. I than adjusted the mesh to achieve the different muscles definition given by the actual pose.
