Here's a MOC I made a few months back after seeing some good ones here. It's not perfect, and obviously i don't have the pieces to be picky about the colours. But still, it's pretty good, i think. Enjoy
This looks very good, but one thing you could improve (other than colors, sometimes that is hard) is the length. The assault rifle is longer than that. It is still a great try at making it (I tried it myself and it is very difficult to make), so I give you 3/5.
