Oh god... poor purple Link...

I really like this, but it looks like you threw too strong of a sharpen filter over it or something like that. Somehow something went wrong with the aliasing.

Amazing drawing though, I love the colors and values.

The lighting in this is amazing. I think you should look more at how much light reflects of Link's face in certain places compared to others. By adding some more lighter values, I think it would more accurately represent the light coming off Navi. Other than that, no complaints. You color work is beautiful, great job.
