Hi guys, someone asked me what brushes I use, so I thought I’d share it publicly! I use Paint Tool SAI for both sketching and painting (PS for only color touch-ups at the end), so here’s my four trusty SAI brushes! I only use these four, so hope it’s helpful!
#1 (Brush Pen) - for sketching & fine line work, ex:

The black lines & the shiny highlights
Also used with Bristle setting (instead of Simple Circle) for hair

#2 Brush - my most used brush of all. Almost all the brush strokes you see are this brush!

All the skin is just layers & layers of Brush strokes to blend
#3 Marker - my second most used brush. Used when I need to cover a large surface area or want less blending. I usually use this first and then use Brush over it for a bit more depth when painting skin, but I also use it a great deal for hair!
#4 Oil Water - I only use this for blending backgrounds, usually!
That’s all, folks! Hope this is at least a little bit helpful!!
