I wonder what the painting would look like if you only use 3 colours. To be honest, I like the first picture more than the end result, especially the eyes are way more interesting. Somehow, they lost their magic and ended up sad.
Will you make a second one? Perhaps with dark hair?
This is one of those exercises where I liked the final result the least. Still, halfway through what I painted, I got a little bored. Art is mostly an expression of the feelings of that moment. Then I had to correct things, sleep discouraged me a little, and finally, here we have this final exercise. I learned things, and that's the most important thing.
