Ok. I'm accepting now. Yes it looked like pixels becasue it was small squares, but that's not enough criteria for "pixel art". I'm not certain what techniques you used for that animation but how it looks and the amount of individual colours suggested ussage of some NPA tools leading to blurry results.
Please change the non pixel art background. If you are not able to do edit it or replace it, maybe the only way to have it on Pixel Joint is as sprites only?
