I certainly don’t intend any criticism of your first efforts. I am pretty new with Blocs myself and sometimes fall back on Rapidweaver that I know rather better. There are definitely some more experienced Blocs users doing great things though.
As a general observation, don’t be afraid to make more use of space, so the layout can breath. Art directors love space and it will help to maintain a less cluttered look.
I am terrible with these things, in the sense that my websites are never finished, because I seem to be endlessly tinkering and making tweaks. It’s overkill to the extent that it’s not necessarily reflected in business profits. No doubt you’ll be able to produce a good looking site and get back to your real work.
EDIT: I would have that top bit of text starting “Leeds photographer, Simon Vine” aligned to the left.
