Background and Enviroment Design

I am currently working on a project that consists of designing Taiko drums found in Japan. It is said the drums are able to frighten evil spirits and the sounds the drums produce are known to be the voice of Buddha. Anyway, My assignment is to model and texture these drums and to eventually create an overall environment. Here is the reference sheet I will be using. What I had in mind for this project is to create a tropical jungle; I might create small village that happens to get caught up in military affairs. Here is the work in progress thus far.
