You should really explain this piece to avoid the possibility of more criticism. I fully understand that if this piece was created to picture a tribal village in the Amazon. However, if this really was created to represent Brazil... :/
top rocks are too flat in the bottom of the platform and stair does not looks realistic and background needs improvement and the darker green loots too much alike dark brown you should make it lighter. this monochrome palette kills me lol.
You are wrong... 
this is the place where I live. If you think brazil is amazonia then your ignorance its not my problem.
Yes, because Brazil is a forest, filled with crappy houses, birds and bananas.
Way to go on the stereotypes.
Philippe sucks.
