I liked seeing the build up for this piece. Are you using a screen capture program or is it a feature in Krita?
I think if you're very comfortable with your krita brush you should stick with it, but then maybe experiment with different tools once you've drawn the figure with the tool you are most comfortable with.
I use the Windows video capture :D (Windows button + G) .... it's apparently to capture game streams but it acknowledges art programs :D :D :D
I used to experiment with a lot of the brushes, but now ended up very attached to the Tilted Pencil hahaha
Thanks, Ed <3
