I actually like the gun better than the sword. I know it's hackneyed, but I think yellow stripes on the sword would look better. But the orange and grey gun is cool.
It has potencial, I take it, wolves here? The only thing that detracts is the gun, I dunno if it will go well with the rest of the scheme. Now my advise, ask the person who will pay quid for it. If they like it, you found it... customer is always right. (I'd sugest doing the gun the same color as the sword... ie red)
