Be stronger. Be braver. It was a great choice of subject. I want to do more portraits with subjects just like this. I love the wacky underpainting and background. Going to keep doing more of that. Get the lines right before you ever start. Check. Measure. Check again. I like using wacky colours even for stuff like skin and hair, as long as the value and the temperature of the colour is correct then it's more fun and more effective than doing the skin with pink, the hair with brown. Paint what you love.
