Great job! My personal favourite is #3 -- Giles and his true love :-) I also really like #7 and 10-variant. And the image you picked for #8 -- love Ethan's expression!

I'm not really one for subtle shades myself, but in a few of your icons I feel the colouring and contrasts are a bit on the harsh side (in particular for #1, 4, 9). But I guess that's largely a matter of personal taste. In #8 I think it actually fits very well.
