Chrno and Rosette

This picture took me way too long and it didn't even turn out very good. Around the end, I started getting really annoyed with it because I was running out of ink and I have no idea what happens when you run out. Also it wasn't turning out good and there wasn't a way to fix it without getting rid of all my hard work and wasting lot's of ink. By the end of this picture, I am left with 17% ink left.
But I'm happy it didn't turn out too bad.
I have no idea why there is a pinkish-white line in Chrno's hair but it upsets me.
