I'd think about describing more than saying he's great/they're great, and find a balance between saying how creative they were in some posing ideas and making it sound like they did the posing more than you did. Blog entries usually seem comparable to a journal entry, if this were for another purpose it could use proofreading/editing.
To me these look quite processed, at least I found that's the first thing I noticed and to me it shouldn't be so noticeable. I love the composition of them in front of the gate but they border on looking somewhat artificial or almost photoshopped in, they look so bright compared to the surroundings.( I think that's what makes it seem processed, they don't look like there were in the same light as the scene).
The first one is the most light gray but those all seem grayscale rather than B&W(I don't see much if any black). I'd think about foregrounds and backgrounds too, the first one has a little clutter and goes a little far to the left out of focus. I like the one of the boys in the background but off to the left there's a post that's a little eye-catching. I like them on the steps expect for the hazy blob that obscures so much of the older boy.
There's one in color of the younger boy that's a lot of flare, maybe a little too much of a good thing? The parents from behind is an interesting composition, I think it works because of the way they're posed together, but I feel like I'm looking thru a haze (and his sleeve looks transparent - don't know if it was how strong the light was from behind or the processing or exposure or what).
The two boys on the bench - where'd his left foot go?? lol I'd watch for that kind of thing when you're framing shots because that's a fun composition. You seem to engage your subjects well to get good reactions from them on camera.
