Some shots with the strobe

That is just wonderful. The little girl steals the show!!! It's nice to see a positively expressive family!!        

 

Mike - those are darling!

 

Great family series!

 

Great collection you got there - strobes make such a differnece eh

I like the first one (group shot) best

 

Good way to start, Mike!

You've caught some good expressions there. Large group shots are a nightmare to arrange, and everyone is in such a hurry! I think eventually, to bring your portraiture to the next level, you're gonna need to add a 2nd light or at least a large reflector to get the fill you need on the deep shadow side. When you ty to cover all the facial area with just a single strobe, many times you get less than optimal results. Love the kid's shot where she's pointing, but would've liked to seen her pointing hand in the frame. I find ya always gotta frame looser, then decide later how much to crop out or leave in.
In that 1st group shot, Granny & Gramps, the boy in the blue shirt, and the guy far camera left needed to be a bit higher, by having them stand on something stable to get them up to about the same height as the ppl camera right. Actually, a pyramid arrangement with Granny & Gramps the highest in the frame would've bee ideal. Also, the woman in the yellow is casting a pretty big shadow on Granny. Looks a little tilted. On that last one, I would've brought the camera up to a slightly higher perspective, or at least done a little creative pruning of those 3 or 4 distracting Geraniums in the forefront. You could've cut them, then still placed them in the frame, but lower and more towards the very front, where there are none now. This might not've been possible though.
These are just my opinons, and not everyone will agree with them. Listen Mike, when I screw up my group portrait shoot tonight, feel free to pick it apart too!  

 

The light looks very natural and you captured the emotional candid feeling perfectly. I was trying to find something I could add for improvement, but overall I can't find any faults in your technique! Great job!
