Thanks guys. I played around with the cropping of the first one for a while, and wasn't really that happy with it, so I'm kinda pleased I'm not alone in my thoughts!
I see what you're getting at with #2, but it's exactly 'as shot' (I was leaning over the side of a staircase to shoot it: it was growing from the side of a tree trunk). I like the bokeh in it though.
