What do you have in mind for the style and theme of the web page?
white background for text of the blog,
900px max for main width of the site,
800px width photos in blog could be.
UI designer already made a prototype (see attached files), now you must draw real design. Its for russian website, but you can make it on English, later we change text on PSD file. See English version of prototype (red font - translation).

Dont use many different fonts. Better to use some standart font that also has russian version
