There's a hundred different things that make this so gorgeous. I can compliment your use of pink and how it is bouncing off of all of her features and accentuates her flushed cheeks or even just the right amount of unpolished strokes that give it character. But my favorite part is probably that you captured that subtle glisten in her eyes of unshed tears that she's determined not to let fall. That was just a flowery way of saying that this is beautiful work! As is everything else you do.
Yeah, I totally over did that pink! Her scarf was pink and my intention was to just highlight it and pull a little of it into the background. 2 hours working on the background later, boom, ALL THE PINK. Heh
