Hooray! I finally got a decent scan of my Angel portrait. I really like the way the hair is lit up. I started by sketching gray very lightly around her head, then erasing the hairs with a sharpened eraser. Then I sketched dark gray around the hair.
The dress was done with lots of cross-hatching, and the embroidery with small, quick strokes.
I'm going to give this drawing to the girls' parents soon. I hope they like it. Thanks to Arpit for letting me use his beautiful photograph.
