Credit to original Van Gogh painting Starry Night.
Created using Pixilart.
Hi! I talked to drea on another platform and we explained how I had to upload it as a png instead of a jpeg
Thank you for your support. I've talked with the people who thought this wasn't pixel art and was the original but pixelated on another platform and the issue was that I was saving it as a jpeg instead of a png and that was automatically blurring the edges.
This can be as Drea said or giving the you benefit of the doubt you could be exporting images as .JPG wich compresses them, in that case try exporting as an unscaled .PNG and upload again
