I'm not sure if different versions of the game have different backgrounds, but the version I played did not use this one in the first screen/level.
The lighting is the main problem with this render. Everything has basically the same color. You need to create more contrast. In Rayman everything is very saturated, but here you can barely tell that the plant on the right has fruits on it.
Other than that I think the arm statue is lacking some shape, and the tings look a little odd.
