the third looks the pick of the night time shots……though at this scale its hard to make out details. I’d imagine a large print would be quite impressive. I also like the quiet atmosphere of the fourth shot quite a lot.
Agree with Liam, hard to see the details at this size.
Been to Prague several times, probs my fave city – well maybe not know its turned sleazy and full of stag parties.
Some processing on the first might reveal more details
