Or maybe it’s good enough for the collab right now, and you could spend that time fixing any of the dozens of other images that you previously rejected that still need help?
 
Besides, you’re missing edits in the images with your replacements - At this point you seem to be just replacing images that don’t break any rules because you have a tool you prefer for resizing things, and are assuming that everything is just resized without any other work being done on it.
 
Anyway, IIRC Joey already looked at this one along with the batch that he asked for help with, so please let it be.
 
If you really have time to redo this image, please grab one of the other images that you rejected where the uploader is still waiting for help, and help that person, or any of the images that are too small based on their size and yet also have the collab tags - those images need help, too.

Holy textured jpeg artifacting, Batman. Hilariously enough, w2x considers part of the texture to be artifacting as well. I’ll need to manually finish the results of better upscale (i.e. remove traces of white where it doesn’t belong), until then, this image will do.
