The first...

...is a detail of a riverbed, sculpted from concrete. The majority of the work pictured was done by me, the paintjob, however was not.
Here is the work it it's final environment.

Trees plants and all. The scene dressing was done by other very talented folks on the creative team.
The following represent the process of painting a T-Rex, I had no hand in building the creature, but as the first picture suggests, the original paint job left much to be desired...

Here's an early stage after the whole thing had been gone once over with primer, and the next stage of the basic black patterning was almost complete.

Then, the final paint job and lighting in final envoronment.
