I had some recent rejections for replacement that are better than what it was posted on Twitter so I want another revaluation.

As always, larger filesize != better
Contact whoever rejected it, you can see that under the "Events" link on the left of posts

Very rarely, I've gone to trouble of checking details like artifacts, quality of lossy compression versus a (smaller resolution but clearly JPEG is upscaled because even blurrier when zoomed in) PNG, and still possible to get rejected. Make double sure that it actually is a superior version. File sizes and resolution are not 100% certain indicators, especially with some sites converting them to 'help' or people submitting screenshots from a higher-resolution phone than the original image.
