I made it this a long time ago when I was running a background focused Discord and just generating tips and paint-overs on my lunch breaks. Hope this helps some!
Ay a couple more tips! Feel free to ask me anything on painting anytime. I don't mind making guides how I break stuff down and sharing my painting recipe book.
I usually don't post these cause I use this as a warm up before I do a bg but hey hope this helps on how I train for efficient strokes. Also it's a fun little brain teaser and gets me moving my brush in interesting ways to make more efficient shapes!
To practice efficient brush strokes so I can do studies like this, I take the time and do stuff like "Can I paint an apple in 10 brush strokes? How about 5 brush strokes?" and it's helped me a lot with speedpainting.
