Ahh I see, it'd be difficult to show every single edit I've done in a normal step-by-step,, but it also doesn't help that I basically tried a bunch of different things randomly to simply see which version would look best :I Many of the filters I used, were then set to like 10% opacity to be careful not to distort the general image quality too much.

Amongst those filters were a subtle gaussian blur, some extra grain on the creature to match the grain natural to a photograph. And I'm translating here, so I'm not 100% sure what the official term for the filter in in English, but I also used the "palette knife" filter, and "paper collage" filter,, both again at a very low opacity. The first was soften the details a bit, make things look just a smidge more painterly, and the second was to simplify the color gradients and mimic my style of putting colors against each other in sections rather than smooth transitions.



Then I did like a dozen different minuscule color adjustments, contrast adjustments etc.

The filters should be picked with keeping your own art style in mind,, if I had drawn this with a different art style, I would've picked other filters to match :0
