Nice series.
And this is an occasion where I find it hard to decide if the colored or the b/w versions win.
For the first one I'd go with color, but for the others I'm not sure.
In the second I find the foreground too distracting.
The third - not sure about the cropping.
Number one I find a very nice one - the unsharp foreground
indicates the beholder being a part of a crowd around and I
think thats a good way to show the subject.
