Only post your original pixelart.
Non traditional forms of pixelart are welcome- for example- perler beads, but only original creations, you can't use other artists' art for reference.
Voxel art and styles are allowed, I hope there is will be another community for it eventually.
You can post about pixelart programs and tutorials on how to use them.
