@maloki It is yes, but the most 'accepted'/'recognized' definitions of contemporary pixel art involves a shunning of alpha transparency and dithering involving too many colors and too random a dithering pattern.. or something like that.
The pixel-art brushes in Krita are quite fun to play with, I must say just to note. Haven't been playing with Krita too much lately though; other more urgent put-food-on-the-table priorities have more of my attention r/n..
