Nice study @javicuesta. You did a great job making the face recede and the light shows strong form. Powerful expression. I just started using my sketchbook again to do studies. I realized I haven't been drawing at all other than doing commissions for a long time. lol So now I'm trying to get back to the basics and refine the craft.
Thank you @art-mess. I´ve been neglecting seriously studying fundamentals until recently I´ve found fun in doing studies again. They´re a good way to shake up the lazyness and as you said, refine the craft at the same time.
