Lolz at first i was seeing an awesome circular wooden weapon with blades on the edge being sharpened, and it looked real good.
Now that i know this is suppsoed to be the warden's weapon, i think there are 2 errors:
-It looked wooden because there is no metal circle in your weapon, and the bright purple from the sharpening process has a weird direction.
The real warden's weapon looks more like a metal circle with blades "attached", while yours only has the blades, that seem to be attached to each other, or to that thread-thin sorta golden circle that we can see. If that's supposed to be the metal circle i've been mentioning, it needs to be much wider, as in, more like a wheel, if you know what i mean.
Too much blade for not enough thickness, put short. Here is a pic where you can easily see the difference:

The other problem is the direction of the purp light coming from the stone, all rays go in the same direction, while since it's light, it should go in all directions.
->The fact that it's the way it is in your icon, makes it look like something else than light. Makes it look like the inside of the weapon is wooden. Look to the left of the icon, there are rays of light coming from nowhere, or at least, not from the sparkle caused by the sharpening. Or maybe that's just me.
Overall, colors and details look great though.
