Three card trick

Whilst camera phones are great for serendipitous moments, if you have a real camera ready to roll, then so much the better. I was taking photographs on the Southbank, when I came across this three card trick guy in front of Tate Modern. He was taking money from the tourists. I could see his plant, but not his look outs.
I shot this on the fully auto setting, into the sun, but in RAW. The original picture is ISO 400, 1/500th, F10. Fortunately I was able to take the original picture which was heavily shadowed by the early afternoon sun

and make something better of it. Note the shadows indicating the sun in front, which is always challenging.. Compositionwise, there is a triangle of attention between the gamer, his three boxes and the guy in the striped T shirt. Other members of the audience are suggested by their shadows. Strangely enough, everyone ignored me, as most of the time these guys do not like their picture taken. I tried this in Malta, and the locals definitely did not like it.
