>>2430121Comparing esolah's and yours, it seems all the additional artifacts where removed with waifu2x. Comparing to the original, esolah's compression slightly changed some colors and waifu2x removed some color noise at the edges (more noticeable in the red detail in the neck collar, but it's all over the image). These things are barely noticeable but since you have quite an eye, I just overlapped esolah's edit with the original, doing some fixes in order to preserve the original image. No filter and no compression whatsoever.
