well , I looked at the portrait section ( only ) on your website and I must say its very impressive.....you certainly have the studio set up well and truly sorted out....lovely light control.......and the environmental work is also very very good....you have an easy rapport with the subjects ( not easy with close family , your kids ? ) and so you are going great guns.
since you asked for comments......I would suggest that you start to move back from the subjects and start to include them full length in both studio and location --- my rule on a paid job was to come back with a selection of head/shoulders////half length full length shots with as many moods as the sitter could muster...take some SIMPLE props too....scarves hats sunglasses etc........and in location ( my favourite location by far ) you can seek out interesting places, make a list in a wee book and use them when suitable models come along.......old stables, ancient trees, tatty brickwork , often occured in my shots.
but you are doing real fine.......you have a great photographic future....and lots of fun to come
