The point of this forum is to have your work critiqued and improve, not to show off your work. If you don't intend to make edits, then don't post this in the pixel art forum. Post stuff like this in the portfolio section I think.
Adcrusher, I appreciate you wanting this forum to work as well as it could, but I'd rather see you offering critique or comments, than see you moderating like this : D
The fact of the matter is that it's 100% ok to state that you're not going to make edits, because everyone is still allowed to give feedback on it.
Had he/she said that we're not allowed to give feedback, then yeah, that would've been pointless.
Anyways, my point: Give critique if anything. And it's allowed to state that you're not going to make edits, as long as you don't keep people from giving constructive feedback. Although being ready to revise your own art would be the best, heh!
