Why not.

The first two are old but I like them, third one's recent.

(From the description: I kind of want to go back and redo this, because otherwise, it will always stick in my mind as "the one I did right before I learned how to paint curly hair". Yeah.)

Feel free to crit or not crit or whatever you feel like.

You are on your way to becoming a good artist, but there are definitely still a few areas you could improve on. The face is a bit out of proportion, I would look at it from afar, see what's wrong, and try re-do just the face on another paper. Practice the alignment of the nose and eyebrows, and how everything fits together.
On the other hand, you're shading is very well done, like for the girl's legs in the third picture. Very well done. And I must say, you have put a lot of effort into the hands because they are also, amazing. I couldn't draw hands if my life depended on it. I like the second and third picture in terms of good quality drawing, but the first, his body is out of proportion and I think you need to work on that a bit more. But in the whole, you draw and color very well, just keep practicing :)
