Well, downloaded and tested.
At first glance, it fits its purpose. The outer edges angle should be more closed and elongated, according to many Sai's i've seen, but that's just personal taste.
Opened in Magos, looks well from it, shows up well.
Opened in Mdlvis, 41 vertices and 72 triangles. Looks well from what I can see, Perhaps the bottom handle thing could use less of them.
Did a little test in WC3, well, they're really big with the villager model, but that's easily fixed with scaling. And perhaps they're somewhat more shiny than they should be. other than that, it fits well to it, hence it will fit many other models.
To sum up, good work. It's going to be useful.
4/5, vote for approval.
