Ooo, you use Krita too? You know, other users make downloadable brush kits if you want to expand your artillery.
Also, on the top right corner, there are workspace options. One of which includes a complete set of animating dockers if you're ever interested in making gif images, although you'd need to export the images to GIMP to get them working.
Spiffy art you got here, You've quite improved the last time I checked!
