Disney Roommates black

Me and my roommates as Disney characters
I asked my roommates which Disney character they felt closest to, this is the result when I used the black / white scanner instead of the color
I am not really satisfied with Tinkerbell and Ariel's face. But considering they are my first "humans" they aren't too bad.
I find drawing human faces more difficult, then drawing animal faces.
All well, all good fun
Ow, for those who curious, I'm supposed to be Rajah

Reference pictures I used:
Tinkerbell: pennyx444 [link]
Rajah: hannah-hannah [link]
Simba and Ariel were based on movie screenshots
