NUGGET: this thread is for sprites to share, not show off.
With that approach, you won't get many sprites to be given here; Instead, by providing open sprites as well as example sprites, you can help others along with formulating their own, which is just as important to do, if not more important. The more people can then learn by example and become better, the more sprites in general you will have, some for example, some for sharing. I'll just say, it's a common thing done in the spriting world, and it's more influential and supporting to budding talented spritists than it is detrimental.
You can provide your examples wherever you want. The whole point of this thread is to have a compilation of sprites that are all available to be used. So someone could just look through this thread and find a sprite they needed without having to worry if it's okay to use or not. That's the issue that's going on here.
