Yep, as James said the guy on his knees is a begging for money. Prague has it's fair share of begging and they all kneel like that for hours on hard cobbled streets, their knees must be in a right old state! That shot is on the famous Charles Bridge which is always rife with tourists so plenty of begging goes on along there.
Thanks for the comments too guys, i have to admit i had seen the original shot done before by somebody else i think it was on 500px, i just had no idea it was in a fantastic café we went to. It was a nice moment when i put the 2 together whilst i was there
It's the Grand Orient Cafe if you ever find yourself in Prague, they serve the best strudel i have ever tasted, so good we went twice!
I think i agree with you Carl on number 3, some of the ghosting at the left of the shot could have gone, i would still have ended up with some of people sat at tables though as they were lit quite well in the restaurant! I quite like the ghosting in number 2 though, i'm not the biggest fan of the stationary figures apart from the begger that i'm glad everyone noticed
As i said before though, the bridge is always busy so there's always going to be some people on it. There was even people on there at 6am when i tried for an empty bridge shot
