However, you need to consider a whole bunch of things.
If you want to make a skin like this work, you should use a war paint that is static and doesn't change, no matter what code it has. Examples of this are the Dragon Slayer or the Park Pigmented war paint. It also works with old weapon skins like Coffin Nail, since those don't vary either.
If you make an individual version of this skin for every weapon, although it will be a lot of work, it will look a lot more professional and it'll distract those who downvoted it just for being "edgy".
You should also try to make a better version of the skull icon. It looks rather crudely drawn. If you add a dark grey border around the skull, it'll look far better.
