After 50 minutes and a short break, I continue with the background, I added more contrast using a black pencil (any black pencil) and I compared my drawing with the reference picture.
By doing this I saw, the head wasn’t right: Top part form, connection with the neck form, and shadows were wrong, the beak was also too long,
It is only 1h drawing, so you are not going to have a drawing that looks like a picture after this, only the main form and some shadows but no details. This is nevertheless an excellent practice. Compare your drawing with the reference this way and see where do you need to make corrections, do this with all your drawings and keep practicing.
Send me your final drawing via email after you have subscribed to my email list. I would give you feedback. I also want feedback from you, I want to know if this tutorial was useful and enjoyable for you.
