Hey! Nice portrait! :D Just a few observations: The curve you drew for the nose and the eyebrows is a bit too pronounced. Since the head is facing the viewer, those lines should appear almost straight. Remember that these lines follow the orientation of the head—so if the head tilts downward, then the curves will follow that direction. The proportions feel a bit off. For example, the eyebrows are positioned higher than the ears, when they should generally align more closely. The eyes are also a bit too close together and slightly misaligned. Try measuring your proportions. There should roughly be one eye-width of space between the eyes, or you can use the sides of the nose as a guide to place them. Drawing a horizontal guideline across the eyes can also help keep them aligned. Also, try to avoid shading in just one direction of lines, as that tends to flatten the form. Instead, shade following the direction of the forms—this will help create a stronger sense of volume. Hope this helps!
