That's the crazy thing, Dikk0's style has been like this for years and years, it's more like AI ends up looking a lot like Dikk0's style. It's probably because a lot of models have been trained heavily on their art.
You mean Dikk0 has been generating this for years and years. There's so many problems in their works. The most damning evidence is their "speedpaints" If you watch them, they start with basically the full picture with color, but without detail. For example, here's their very first "speedpaint": https://www.pixiv.net/en/artworks/128694804
Notice how the first frame of them "drawing" is effectively the finished work, without a background, and with significantly less detailed colour. Last I checked, actual artists don't start with a perfect rough work with colour as their FIRST FRAME without any actual sketching or anything else before it. There is 0 sketching done or drawing done in their speedpaints. Both of their speedpaints do the exact same thing and it's so obviously NOT how artists draw.
