Really good work! Watch out for the nose structure. A couple look a bit off but only in a minor way. Try to think about or show more of the underlying structure of the nose lets say. Some noses you show the planes of the nose well and others not so much and they don't read 3d as well. Something to look for is all. I think you may do well to draw from high contrast black and white portrait photos too if you haven't already. Seeing the planes of the head and form under that kind of lighting is so beneficial to study from. Keep up the good work!

good. Keep praticing man

Really nice! Your style could work fantasticaly as an ilustrator. Your perspectives are very well done, and your expressions. But I would watch out for your facial feature placement/size, especially the nose, like the last 3 heads, and some others. Keep the up the great work!

Hi @Guillermo Murillo, Really nice drawings! I like that I can see the "loomis head construction lines" underneath some of the drawings, and that you really tried to understand the concept of the loomis head! My knowledge of the loomis method is not that great though, hopefully someone else on @Proko can help you out with tips on this method. Nevertheless, I think that the facial features (like the eyes and mouth for example) in some of these head studies could also use some more construction, they feel a bit flat in some of the drawings. My feedback would be to study the basic forms of these features a bit more. (And not to just copy the lines you see, but really understand the shapes.) Keep on the great work! I hope this will help you a bit! Cheers, Leon
