Blog header

Dear designer, I need a header for my blog that hopefully includes a logo/signature as well. My idea is like this: Basically it's supposed to be illustrating the place from which I blog. The illustration is part of a room with a window, and through the window you get a glimpse of London with its' many buildings. Below the window you can see part of a desk where maybe a notebook lies open with my blog name written in it. I don't want it to look too cartoonish even though it's okay if not all the elements are photographic. I want it to look modern and sleek, but also inviting and warm . I don't want the illustration to look like barbie is writing the blog, but an intelligent, professional, yet personal woman. ;) So this is my idea which of course can change a bit if a real designer comes along that knows how to do things. I am very much an estethic, and I dream of a creative, unique, personal, yet professional header. That's all. In awe, Kristine.
