After deciding on my shot, I exported the track script to 3DS Max and merged my rigged snake model. I set the image sequence of my chosen shot as the viewport background and used the tracking markers to position and scale the snake.
I will now concentrate on replicating the floor plane and the tree in 3d in order to catch shadows and add realism to the scene. Modelling the tree will also prove useful as a guide for effectively animating the snake so it appears to be around the tree.
