Wow I love the hair strings and the skin texture, especially on the side of the nose into the cheeks! I love the anatomy of the eyes in general, the lower part of the nose and the anatomy of the lower lip and the glossiness and skin crevices on the lips, very awesome!
I thought about a portrait of my little son, two years old. I'll send you some photos and you say me what would be feasible. Whether you rather postpaint a picture or sketch something new. Do you have a g.mail account? For sending some larger .jpg files?
