In general, a very very nice piece. Just as an advice, keep always in mind where the light source is, so you have a consistent shadow direction. In this piece, based on the highlights on the lips , the wrist and the hair, I would say the light is coming from somewhere in the right, but the highlight in the eyes, the lights under the left eye and the highlight over the left eyebrow says the light is coming from above. Just keep an eye on that ! Good work !
Very true indeed. Never looked back on this since 2011. One bad thing you could do as an artist is never to look back on your earlier works. We could learn how much we evolved over the course of time and effort. You've got an eye for details. Many thanks mate
