Hey!
I don't know if you're still active or if you take requests, but I'd really like to use one of your icons for a hero. Sadly, I can't find any more icons to go with it, so if you'd be up to it, I'd really appreciate if you made some more icons along the lines of your BTNHealCannon.
If you're interested, I'd be happy to detail the hero it would go with, or even provide a test map where you can check the fully coded hero out.
