I think this is an absolutely awesome artwork! The detail created by your contrasting tones all in one colour analogue is brilliant. The hair is realistic and the horizontal and vertical lines help to add flow and motion to aid in the total effect. I am amazed that it was done digitally. The realism and emotion you managed put express in a cartoon really captures your attention. Personally i think the effect of the side profile could be complemented with more stars or light to balance the image and relate to the title. Though it is not a necessity as it is already a brilliant work as is.
First off - This piece is absolutely BEAUTIFUL. Tangled is actually one of my favorite movies, too. You did wonderful at capturing the moment. Excellent use of skin textures and hair, and really love the shading and her eye. You put amazing detail into this piece, making it appear simple yet full of effort. The color scheme is well thought out, and you've done an overall AMAZING job! Appearing realistic, yet retaining the style from the movie all the while. The angle of her face, how she's looking at the lights, all of it. All of it is perfect. You win everything.
