I'm very happy with it but many people consider it too pixelated. They don't realize the idea of "pixel art". So they'd probably prefer to see the same white badge but with the edges anti-aliased and rounder on sharp displays, which may require making the f symbol smaller as you can't expand on the outside. I'm not sure making the symbol smaller is possible without blurring it to obscurity. I don't have time to spend another 3 hours on optimizing it.
