Hey there! Not a bad study. But the structure was a bit off. The skull wasn't following the spherical form, so the fron looked kind of flat, also because the back of the skull wasn't defined, so, the oval shape wasn't clear. on the other hand, even though you're not going to refine the back of the skull, paint the form with soft edges so you can suggest the overall shape, and help the viewer's eye to finish the rest of the shape. Hope this helps! | Artwod Feedback
