To start out, it needs alot of details. First you should try adding a wall, and make some clones climing over the wall. You also should add some plates on the ground to make it look like there are small hills or lumps on the ground. Also, you need a better background. I did not like seeing the printer in the background. I did not want to reply because I lost interest in this scene you made. With a few more awsome details, you will have a Aswome scene! Good luck and post some updated pictures.

Good job, I agree with DBH though, it needs more details. Also the pictures need a little more work.
