Thanks for the suggestion! I tend to agree, some details get lost when sized down for the homescreen. Here a version with double the thickness on the strokes. I guess this will count as my third entry 😉

Thank you!

Here are my submissions! I also went with the space/ astronaut lemming theme. I tried to make an icon that would be recognizable & familiar to lemmy, but also unique and fun. I included two options with slight variances.

Update third entry - with thicker strokes as suggested
