It is a beautiful painting, unfortunately, PJ is a very narrow oriented traditional pixel art gallery and we cannot accept it. It has 1997 colours. Maybe if you could take it down to less than 300 I could accept it conditionally, and ask you to submit only restricted palette pieces in the future. I believe reducing the palette could kill the core of this amazing artwork so if that doesn't work the only thing I can say is to move this piece to other online galleries like Lospec which stores not only traditional but also modern and enchanted pixel artworks. It breaks my heart because I really love this piece. Maybe you have more works to share which are less controversial for PJ rules.
Thanks for taking the time to look at it! I should have probably known it wouldn't go through over here lol. As you said, sadly the way I work isn't really compatible with the limited color palette rule on this site (and I don't think it would be a good idea to try to revise to meet the color quota). Thanks anyways!
