I love #1 and #4, the B&W really works well - on #1 in particular. I also love #2 but it's a shame it looks a bit out of focus. I'm not so keen on the crop of #3, it's a bit too radical for me! Overall, really good!
Forkie, Thanks very much for taking the time. That one picture does look a bit soft. I'll have to take a look at the original when I get home. I wonder if I did not apply any sharpening.
