Hi Stuart,
I haven't been on here much in the last couple of weeks, so catching up again.
Car on Bridge : I like the motion blur on the cars - I think you've judged it really well and there's a nice architectural curve on that bridge.
For me though, the people on the right aren't really contributing anything to the shot. They're not sharp enough to give a real focal point, but not blurred enough to give a sense of motion.
I feel like there's a good shot lurking in there, but I'd crop off some of the RHS to lose the pedestrians, straighten it so that the b/g building is vertical and then run the burn tool over the sky to bring out some more detail.
Carpet Man : I'm not really a fan of this sort of street shot, but there's something appealing to me in this particular scene. I'm with Jenny on liking the composition and colours (just a shame that you chopped his feet off), but there's something more than that which draws me in. I just don't know what.
However, I don't think that your problem is so much with the DoF being shallow, it looks like you've missed the focus slightly. It seems to be on the foreground carpets rather than his face.
Girl on steps : This is a personal thing because I don't really like candid street shots, so I find it quite hard to offer any comments. The one thing that does stand out for me is that the focus seems to be off on this one too - I'd like it to be on her face.
Thing?????? from this week : Absolutely no idea what it is, other than lots of shiny metal
I think you've missed out on some interesting abstracts in this one. Get in close, and make the most out of some of those curves and shadows.
