Another update!
Worked more on the lighting (its still a wip and a test one). Also placed the scorpion and polipainted it. Thinking to make rests of another column to put it near the camera with the scorpion and play a bit more with DOF.
@spaceboy412: All the vegetation are Maya Brushes, you can select a geometry and paint a brush over it (you have lots to choose). I have mainly selected the ivy one and then tune it to have the shape and density I wanted, converted it into poly object and make a new Uv for them (to have more than a leaf texture)
