First try at B&W

[Pink Dragonfly]

This was nice in colour, so I thought I'd try it in B&W!

The composition there's not much I can do about, there was a lot of other kids around and I had to get rid of odd bits of arms, legs and what have you... I just really liked the expression of this girl, deep in thought.

I'm not really sure how to convert to B&W - this one is the colour image desaturated (I'm a novice at PP), not really knowing what else to do...Is there a better way?

I've sharpened it a little but I'm very unsure of what to do with light and contrast?
