Bumposaurus, the one thing that struck me about the pictures is that they don't seem to have achieved the 'magic lens' effect that most estate agents achieve, you know in making everything look a lot bigger than it it - if anything I think they've made your house look smaller (have recently moved out from Putney so know the type of house and area well). On that basis, and hopefully being constructive:
I would definitely make them take some more pictures of the kitchen, maybe from the door of the utility room - from the angle they've taken it you can't really see how the kitchen would 'work'. Also, so you have a more chairs for the breakfast bar? I'd put them all out (even if they are only highchairs) becuase at the moment it looks like you can only seat 2.
I would also get them to take another picture of the front of the house, face on - I know it's probably tricky making sure there are no cars parked outsife, but the current picture doesn't really make your house jump out as being the one for sale.
The picture of the bedroom makes it look small (if it's the master bedroom, then it looks smaller than mine, even though it's actually larger)- again no idea of how furniture would fit in. and maybe a bit of additional 'warmth', perhaps by putting a picutre (as opposed to a photo) over the bed.
Also for the picture of you back garden I'd get them to focus on the eating area at the back. It looks like it catches most of the sun.
Hope that doesn't all sound too mean. I got a second set of photos done of our place when we sold, and it made the world of difference.
HTH, and good luck with the sale.
