>>1998178I really don't see what I'd call "pixilation".
I _do_ see a fair amount of color-irregularity in those areas in your original.
I applied a filter called "smart blur" which smooths out minor variations while leaving distinct edges alone.
I saved it as V1, then ran it through Waifu2x.
Does it look any better? My file-size is smaller than yours, indicating simplification.
If not, could you post an extreme close-up with the problem circled?
