I took this image recently and I quite like it for the slightly mad contrast of the both the deer and the cricketer - both completely focused on their respective, if slightly incongruous, activities!  I was out trying to take images of a particular group of trees in my local west London park and it had not gone very well so I was walking home a little despondent, when I came upon this scene completely by chance.  A few seconds later and I would have missed it.  I am not sure whether this is wildlife, documentary or 'street/park life' but it's got a deer in it so I am submitting it as wildlife!
