The only comment I can suggest that hopefully you have time to implement is fixing the auto expand to a set size. If your banner is 769 in width, so should the blog widths. With WordPress it can be accomplished by editing the CSS file. Currently the banner looks out of place on anything larger than 800X600 making the top navigation and links get lost in corner of the banner picture.
Other comments to think of:
It would seem that the blog covers a range of items but does not focus or specialize in anything in particular. It seems like more of a friends and family blog. If that is what you are going for.
Colors and font sizes for the navigation are a bit small for me. One alternative would be to check out Free Word Press Themes at
Theme Viewer. You may find one what suits your needs with the proper CSS already completed.
