I concur; I like the second one most, because it has emotion on the face.
You should shade your drawings! The sides of the face and the noses would give these depth if they were shaded. The eyes look a little strange to me in all -- I'm not sure if it's how thin the eyebrows are or the lack of eye lashes. The hair could use a bit of deeper shading to contrast as well.
Well done -- I really like the second one.

I think you have a brilliant talent for drawing and I adore the features of your work. I think I'd have to agree with Juni and say that the second one is my favourite. I think this has a lovely feel to it. The slight smile makes me happy and it's a feel-good thing to look at, so I enjoy it very much.
A little nitpick I have it the features of the nose and "moustache area" (XD) which I have to say I have the same problem with. In your third illustration I feel it lacks realism and perhaps as Juni's suggested a good shade might ripen it up and tone down the nose features.
Saying this, I do think in your second picture you've PERFECTED these features and I have to say it's adorable!
Your hesitation suggests you are trying to protect my feelings. However, since I have none, I would prefer you to be honest. An artist's growth depends upon accurate feedback. — LCDR Data
