While I'm working with cmms, I had an idea to release a pack of 4 free pixel banners for FA, so that people could decorate their accounts

Suggest your themes, I would be happy to consider them and perhaps your theme will become an idea for work in the pack c:
For the first theme, I would take "Sea, Fish and Corals" (a little bit of self-interest)

1. Sea, Fish and Corals
2. Caves, Lava and Crystals (new)
3. Сosmic Infinity (new)
4.

(However, given the current workload, they will appear closer to the end of September)
