You are asking, so here's some constructive criticism:
The LED display really distracts me, how it sticks out. It was a good idea, but I think to really execute well it you'll have to make some big modifications to either the display or the gun. Other than that, it's not a bad looking gun. The magnetic holds are also a good idea, but when you can see them, it's distracting too. If you're going to try again, I'd put them on the inside to hide all the glue and whatnot, and if you've got armor (or are making some) put them on the inside of that too.
