Awesome work! And a great way to get to know Krita. (I want to do more master copies myself.)
By the way, you may have already come across some of these resources, but there are a ton of brush packs available on krita-artists… if you feel like tumbling down that particular rabbit hole 
… though I know I intentionally avoided anything but the default brushes for a while just to get my bearings, haha. (I’m still pretty new to Krita myself – been using it for a few months now.)
In particular, coming from a traditional background and following a more traditional process, you might find the Memileo Impasto Brushes interesting. I’ve barely scratched the surface with them myself, but I’ve seen some really impressive work done with them!
In any case, welcome!
