No I have not, and yes, Sheezyart is retarded. I'm saying it's retarded for not featuring me; I'm saying it's retarded because the art that's featured is generally pretty mediocre and there's much better art on the site. I'm really not sure what the standards are for featured stuff.
The standards are the first thing the mods see that isn't completely terrible. And they don't even care anymore; the featured artwork should have been changed months ago.
