For anyone questioning, I tried to save the render as a transparent png, but when I opened it in my editing app, it showed up with a black background, instead of a transparent one. So, I did what I could.
You’ll likely have issues with the text at smaller resolutions. I recommend trying different ways of making the text stand out more, and also work when the image is decently smaller (group page uses 128x128)
Aside from that, looks incredibly polished and well done. Impressive work on making the most out of losing transparency. If you don’t already, you should save the project files and use that to export to PNG under a different file name. That should be a saving grace if you ever have bad export settings and it turns out pixelated or loses transparency.
