Heh, I was asking how you did the lines because I have been trying to get rid of pure black lines in my own comic :3
Anyway, you can dissect my work here.
Anyone can also use it to build more (in case you wish to try and don't feel like playing with the flats)
Pastel... what kind of brush did you use to get the light effect around the moon? It is divine =D
And your hair is awesome as well, I need to get better with highlights like those.
That is very nice of you to lend us the file, hands on is always the best way to learn art!
