I have tried to remove the "jpeg noise" yet I am not satisfied with my result :

[EDIT] 2nd test → https://i.ibb.co/zWC6WcsG/test-small-2.png ← ?

The original file is massive, sadly, and FA doesn't want to let me upload it. But newgrounds has it in the original no problem, much clearer; https://www.newgrounds.com/art/view.....ence-adventure (I draw at stupidly high resolutions I've realized)

Your second one works good :D

Thank you for the link ! In order to obtain the second one I have created a larger image from the jpeg one on FA and I have filtered it using a "Selective Gaussian Blur" (with GIMP) than I have resized back to 644×1280 pixels.

The "larger" image : https://i.ibb.co/j9JMN26f/test-large.png

I am now wondering if by changing the interpolation values to resize the original image to a smaller version (and saving it as a PNG) before posting it on FurAffinity wouldn't be a solution...

Here are two tests of resizing (1209×2400) with GIMP :
- https://i.ibb.co/0jYGFzVs/test-1.png ( interpolation → "NoHalo" )
- https://i.ibb.co/Y7vQXBgt/test-2.png ( interpolation → "None" )

Super adorable characters in a laughingly cute attack pose.they will not get any trouble from me as I would offer to tag along as a rat mage to help them on their journey and maybe massage those feet As a bonus.

I really dig that troll!! They came out great! Those paws are fantastic 🐾

Very nice indeed.
