Good! B&W is nice, just don't overdo it and think that any boring image can be turned into art if you B&W it! :mrgreen: (not related to your photos, just a general observation, it happens)
Another thing, when you have a group of photos that can be considered a series, ie they are related, it is much better if the processing looks the same in all of them. If they have the same look and feel, they make a stronger impression as a group.
In this case, #1 and #3 share the same look, but #2 really stands out. They were all shot together i assume, but #2 looks very different because of the processing. No matter what look you settle at, it is usually better if you process all photos of a series the same way.
