I think this shows great promise!
One thing for the future would be to out the focal point (in this case, the Maxim) on an angle compared to the sides of the base. It only has to be slightly, but can remove the sometimes 'contrived' element of the scene.
The leaves have good tones, but the spread I think is too even. I'd go for some clumps especially directly under the trees, and pressed-in leaves where there has been traffic, such as behind the gun. I would also be careful in future as to the height of some elements (in this case you front tree) and where it is placed from a viewing perspective, as it can block the view of the contents of the scene behind.
Keep it up!
