@RT7 Just wondering, what adjustments are you applying to the image apart from cropping/rotating? This cutout and this one both have something weird going on with colours/contrast compared to the source images, where the colours look muted "flattened", like in this cutout from two days ago I redid, but not quite as noticeable. I made an example below to show what I mean, on the right is your cutout and on the left is an edit I made, where I used some adjustment layers to try and fix the colours/contrast, but it still lacks some detail compared to the original image. Is it possibly that you're letting remove.bg resize the image for images larger than 500px*500px (0.25 megapixels)? When I first started using remove.bg I noticed that colours were sometimes edited in the resized version of large images, but not when I manually resized the image in Photoshop first.

Here's the same comparison with the the original image (no colour correction) on the left and your cutout on the right

A bit of highlights, because otherwise the images appear dark and grayish

And are you doing it with Photopea, or Photoshop/paint.NET/GIMP? There's probably a different adjustment that will get better results
