Baz, the smiley one is just a bit too happy ... like your dying to rip into some customers bank account

The serious one is .... ummm, well, just a bit too serious, it presents to a potential customer like, this is me, a super pro photographer, and taking your pic is gonna be a really big serious deal and its not going to be fun

Like most have said before, try for a pic of a "contented happy Baz" with an expression between these two. "Cheese" is not the right word... ha ha
