Good start to the picture!  You are doing the right thing by trying to tell a story, and place it in an appropriate scene.  Big points for undertaking the project.

Feel free to accept, change or discard any of the following ideas. 

First thing I would do is adjust the relative postions of the figures.  As it is, they too closely mimic the upright trees around them.  You probably want to show more of the emotional tension betwen them.

For the male: extend the right leg backwards, as if he just stepped forwards to touch her shoulder.  This will give him more of a curved line. Extend his right arm more to indicate the 'reaching-out' motion.
For the female twist the upper body to face the camera more, as if she is turning more towards him.  Then move her whole position so that his hand and fingers are just barely reaching her.

You will need a little bit of lighting to highlight the figuresa touch more...possibly using a light-gel based on leaf patterns on a spot-light to create a lone beam of light that hits them.

Finally, either add a bit of light and texture to that left-hand front tree to show that it is a tree, or get rid of it....the solid black does nothing for the picture as it stands.

I hope some or all of thses suggestions help you.  Looking forward to where you decide to go next with this picture.
