I am afraid none of the pictures look like mine.
I took a very quick snap as I left for work in the pouring rain.
I will try to get some better ones this evening if it is dry.
I live in a bungalow so no upstairs rooms to shoot from so this was taken whilst jumping - sorry but better than nothing given the circumstances.
