Yea finding good brushes that work well and are likeable to download can be such a drag sometimes.but medibang is nice from what I've seen. I have a friend or two that use it too, but they draw privately so I cant really link any examplesWhat they like to do though is take photoshop brushes (since there's such a large selection) and convert the into a simpler format like png so they can use them in programs like gimp and medibang. If you ever feel like doing that I have a few brushes I can recommend(Some don't work as well with the program swap but it's worth a shot if you ever need some more brushes)
