I actually really like the last one, with the vague globe and trees, and I think it would work for the page header and other places where you can see it clearly, but I think the two more cartoonish ones would stand up better to being shrunk down to the browser's tab bar. Of those two I like #3 better than #1.
Okay, last one before I actually get back to work: 🙂
Cropped and zoomed so it works as an icon with the mascot still discernable, and looks nice when the server masks it into a circular shape, but you can still see the curvature so that the "world" theme is faintly present.
Yah I like these too. I like my world icons enough that I feel like maybe the official Lemmy graphic over one of my worlds would be nice, but also, I'm not sure if there's even interest on @Ruud 's part for any of this. So IDK how much more time to invest in it.
Also, I just like using AI to make icons; it's enjoyable for me. 🙂
