Those landscape drawings are looking good. I also applaud you for drawing/painting traditionally - it definitely takes a different skill set than doing so digitally. The only feedback I can provide relates to your head studies. I see that you are currently practicing drawing the planes of the head. I would suggest also studying the human skull and rotating it in space. I say this because the construction of the human skull helps explain a lot of the planes of the face, with the few remaining ones explained by facial fat pads which is something you can tackle thereafter. Hopefully, this feedback comes in handy. Until your next post, I will anxiously await more of your paintings
