I decided I don't really like the icon for myself, so it's for the taking to those that want to use it. I'll have to make an icon for myself sometime.
Da's default size for icons is 50x50px, you will have to downsize this icon by half. I left it bigger so you can use it on other sites that support larger icon sizes.
And by some chance if you find out how to edit this, go ahead, here's one way: Use alpha channel and load channel as selection to select, invert, make another layer above the base image, fill, deselect, delete layer below, make another layer below newly filled image and choose simple color. DA would not take the transparent version because it's too big. (pff, fix this DA) There might be some things you have to change (such as fixing the blood color, since you can only fill with grayscale)
