You've got some gradients in the sword blades, and barely any contrast with them.
You need to define the blades and handles using less colours (which can allow more clear-cut contrast) and less black outline so the small swords don't have cluttered, black handles and the big ones aren't just solid gradients.
You really do not need 2 shades on the brown backs of the shield, especially when you shade them like they're convex, when they're actually concave.
Lay off on the details in the shield, as they're extremely cluttered.
You should also just dive in and make the shields custom.
You made the swords custom; I don't see why you aren't capable of making something as easy as a circular shield, too.
Please also shrink your credit tag, as it's bigger than your actual sheet is.
