^ Darren, very nice portrait. As are others on your Flickr page.
Here is one I did last weekend. It was a family portrait session and this was the last shot of the evening. Sun was getting low, all the kids and grandkids were on the patio. I got dad to leave the grill long enough for a couple clicks. Einstein with mid sized PLM soft silver with diffusion panel. It was probably 15 feet away.
the horizontal lines in this photo are distracting. the retaining wall is close to horizontal but the pool edges keep grabbing my attention I would use adaptive wide angle to try and fix those
