Wolfwood VS Vash - char design

Alright, I have been trying to draw without references. I took some notes and went with those.

Wolfwood:
- pupils are very small
- eyes are smaller compared to most other characters
- wrinkles under eyes
- in general, kind of sullen, otherwise sarcastic or angry
- usually slouches
- lines on cheeks
- unlike Vash, Wolfwood's eyebrows aren't necessarily connected to the top lid of his eyes. Vash, however, almost always has an upper lip bordered by an eyebrow

Side by side comparison:
- You can see how much smaller Wolfwood's pupil and iris is drawn. Also, wolfwood's iris is usually only outlined halfway. Most other characters have the iris outlined at the top and the bottom, where it comes into contact with the lower lid.
- The noses are pretty much exactly the opposite of each other. Both of the lines that make up Wolfwood's nose in profile are slightly curved outward, whereas the lines that make up the nose of Vash and most other character in the manga both curve inward. When nostrils are hinted at, the top of Wolfwood's nostril is outlined, whereas the bottom of Vash's nostril is outlined.
- Shape faces: Wolfwood's face is more angular, where as Vash's face has more curves. Also, I have noticed that with this face shape alone, you can almost go from front view to 3/4 view with no problems. Just put your center line in different places.
