I agree with STEELBACK, you should provide WIP to prove that this icon is drawn freehand and applies to the icon submission rules of Hive.
It looks like a photo, not drawn. Tho this does not have to mean this is not freehand.
I also agree with Kingluis, the background looks weird. I also would recommend to change it to black, as most warcaft icons are designed this way. Green looks distracting and does not really match Warcraft.
