A very good concept, and an alright product, but I'd say consider this a base to improve upon. Improve the wood, get a couple better pictures, and, as Jay said, add in a custom sound for it.
Also, change the rating criteria if possible,as you're not providing a custom model or animation.
Uh not to sound too harsh but it doesn't look very wooden, and it's way too colored/brightened. Your heart is in the right place, but it's too bright for my taste.
Also, try adding an AK sound like I did in my version a while back.
