Upload & Sell: Off
Gosh that's a tough on Tony. Looking through I honestly can't say any make me say "That's a Tony Hart photo". Perhaps 20 could work. There are a lot of nice couple portraits, which your good at, but if you're trying to sell PJ amongst the other people, I'm not sure that would be the right choice.
as an alternative, keep to 3:2 ratio and add a space with your logo above / below. I think the full shot of #6 could work well like this.
P.s. squares are evil. Perhaps you should start instagraming at weddings ;-)
