I totally love this great job.... ... I think nothing needs to be changed.... except even though Rapunzel is in the dark i think you should have done some thing for the background.... like maybe having mother Gothel's scary face kind of appearing or just something that is kind of spooky that would fit with this picture and great job with her hair .... but overall great color, shading, and good lighting with how the candle kind of lights up Rapunzel. O and I hope you try this with Flynn Rider too. And what did you use to make this art supplies or software.

LOVE IT!!!!....
