Quick portrait drawings

Hello five family,

I wanted to share a few sketches with you.
When I started to feel like losing all dimensions when I started to color in my recent works, I try to draw a little more to understand the dimensions at the sketch stage from the very beginning.
Christmas is approaching and my attention is very scattered at this time, but I still try to draw as regularly as I can.

I drew these drawings in photoshop. And I drew it during my twitch stream.

Thank You
