Logo design

I have been asked to design a logo for a new compony called Studio 7 Photography. I will also be creating business cards and mock ups of where the logo will go. In return the client said i would get a free photoshoot.
So i set to work doodling and coming up with various ideas that did and didn't work.

Unfortunately the client has said that it needs to be the number 7 rather than the word because they have already bought the domain name with the number in it and they don't want people getting confused and not being able to find their website. It would have been nice to know that before I started but never mind. I much preferred the ones i doodled that had the word as i thought they worked much better and the word gave space to do much more with. so i had to have a rethink.

I came up with this which i think works quite well but when i showed it to the client they said it was much better but still not quite what they were looking for, unfortunately that is all i got, they have not been particularly forthcoming with constructive criticism saying what they do and don't like about it.
