Interesting icon, but it just doesnt fit as a war3 icon. Maybe if you added a slight variation of light in the background, so that it isnt plain black.
Also, I like your handle. The handles seem to be the best part of all of your icons.
This is better than 3/5, but not quite 4/5, so I'll give it a 3/5 and raise it to a 4/5 after you've improved it a bit.
