Mysterons

I'm a bit behind with blips, my son Chris is up this weekend and we have a full program of activities.
On Thursday, Jess went to Carlisle for a few "bits". I tagged along and went in search of a Peregrine Falcon which has been hanging around the ramparts of the  Cathedral on and off.. Unfortunately Friday was "off"
Other opportunities were limited due to most of the centre of Carlisle being dug up. I retreated to the station for a bit of inspiration and was taken by the shadows cast by the roof ironwork.  These circles on the wall somehow reminded me of the Mysterons from Captain Scarlet back in the 70s.  I waited for a suitable subject to come along and this chap obliged.
I was in two minds whether to take the sack barrow out, I'm not sure if it's distracting or a good juxtaposition giving a sense of the location ?
