Hi toast64, First of all, I really like the vibe of your drawings and how you made these portrait studies with one consistent style on one page. Great Practice! Regarding you question, there are only a couple of things for you to consider for your next portraits: I've done a quick paintover, just compare them to your drawings so you better get what I mean: - I think you should darken the shadow side of the forms more, so their plasticity is more visible. You've already shaded it a little bit with a dark terminator line, but I think it could use a little bit of a darker tone (as seen in the paintover). - I think it would be better for you to use a paper with less texture than you used for the studies. The texture is not helping you make clean lines and it also becomes harder for you to render the shadows smoothly without the paper texture being too distracting. - Some proportions within the faces were a little off. Just compare them to my paintover. Keep a close eye on the proportional relationship between eyes to nosetip, nosetip to chin and distance between eyes. Good luck in your further studies! Joël
