Tintin, Enhanced

I have a new lock-screen background for my PC which is from the cover of a Tintin book, Red Rackham's Treasure. (My active wallpaper is a painting of Guanyin, which you can see in this post.)

I found the Tintin image online, but the quality was not very good. So I asked ChatGPT to improve the resolution, make the lines crisper and get rid of the jpeg artefacts, but without changing the content.

ChatGPT's first attempt (Edit 1) was too cartoonish – flat and oversaturated.

I then requested a do-over, specifically asking it to preserve the hand-painted look of the original, and its delicate, less saturated colours.

Here's a comparison of a magnified detail in the three versions:

If you look closely, Snowy's left year is not quite right, and the black reflection lines on the glass have white segments in between which were not there in the original. But these are things which I could have fixed manually, or through another round of prompts. Overall, I was really impressed with how well the AI managed to clean up the image while preserving the organic look of the original.
