Done for a compositing challenge in the Danish 3D community at 3dmaxer.dk. We had a week to complete, and in the voting, this entry won.
We were given a photo (look further down the page) to use as a plate to put anything we wanted into. My eyes caught the water hose and a cactus that looked human in the background, and from there the idea of a thirsty cactus desperate to get water developed.
I rendered out different passes from Blender, and composited and retouched a bit in Photoshop. Before putting the 3D in, I had retouched the original photo, removing all flowers and giving the whole thing a more worn out appearence to fit the mood better.
This was the original photo that was given to use as plate:
