I'm not here to tell you how to do your thing, but I think your Pixel Art would benefit from having the original image size beneath it.
This already looked great, but I knew it'd look phenomenal at its original size, and I was right~! Like I said, not trying to tell you what to do, but as someone viewing your Art, I feel my viewing experience would be a bit more enriching if a second image, at its original size, accompanied your pictures.
Again, Phenomenal Work~!
