Blue tit

I've been stalking the next door's neighbour's bird feeder for a couple of days trying to bag a shot but without much success. The combination of my movement, the bird's quickness, the low light seemed to result in blurry images.

However, more success today and this is probably the best of the bunch.

It's been cropped a little but could it do with more? Some think that it's a good idea to keep some context in the shot rather than go in too much.

Anyway, I'm quite pleased with this shot but comments welcome.
