I really hate people saying that. I'm sure most people that make sigs use "Render packs"*God I hate that they are called that* so its bound to happen.

Anyways I think Rookie pretty much had it. You blened the stock a bit to much, thats the biggest problem with it. I think if you fixed that it would be pretty nice. The background could probably use a bit more work as well but its not bad how it is. Maybe competely change the text though. Your really not using your free space to your adventage how it is. So maybe bring your typo down, center it and make it bigger to feel up a bit more space.

I think if you do those things it would look alot better.
