'Avril' character sketches

Character sketches for one of my backburner comics, 'Avril, The Fourteenth.' I kept trying to find a style, but it just hasn''t come together too well yet. Eventually. Critiques on what works and doesn't is greatly appreciated!

From top to bottom:
- Avril
- Leslie (yes, he's a boy)
- Danii
- Tim
- Colin
- Hall
- Justice (AKA, Hall)
