Yeah there are still some small problems that need to be ironed out after the Pixel Art/A&D merge. Sorry about that. Yes if you have more than three pieces of Pixel Art, you may open a gallery. Alternatively, if you just have two recolors or fusion, it goes in that respective thread.
And haha, yeah, the link was from my old profile, which was merged with this one, whose link is not that one. It's confusing lol.
I've reviewed the Art & Design rules and I've popped up with a question - is a gallery showcasing three pieces of Pixel Art allowed? According the Pixel Art section of the rulebook, I can only guess that I should abide by the rules but I've not seen any concrete PA rules yet.
PS - the link to your profile at the bottom of the post is broken XD
