Between the pole and the crown part shouldn't be so... ah, bugger what's the word... sharp? It should be a smoother transition to give it the welded effect and not the directly extruded out effect. Also the crown section could use being lowered by a pixel so it lines up appropriately with the handle. Overall great work though.
I feel it would look a bit better with the keychain's end at a slight angle rather than just flat at the screen.
Otherwise this is amazing! I especially like the look of the guard.
