Yeah but pixel art is only a show of drawing (only if it's original), and it doesn't belong in the gallery because it requires no skills in building to make it. It's unfair to the rest of people who actually spend their skills building something, rather than wasting their time on some pixel art, which requires no skills from building whatsoever. It is NOT a show of talent, therefor, does not need to be in the gallery, which is where people show their talent off.
Instead, it needs to be taken somewhere else, where drawing or other forms of art like that are acceptable. Deviant art for example, would be an appropriate place for pixel art. And it's only worth it ANYWHERE if it's an original drawing. Pixel art is 0% skill of any kind when you copy another drawing (even if the drawing was NOT in pixel form).
So there you have it. You can still try to argue with it, but I can assure you that most of all the long time players will agree that pixel art in itself is not worthy of being in the gallery.
