I like photoblogs in general... I also like to see photos in portrait orientation all at once instead of having to scroll to see it all. Consider limiting the height of photos to your target resolution. (Or use javascript to dynamically resize them to the current window height.)

I'm not a big fan of the blue color for links. But personal preferences aside, this is more than sufficient. With photoblogs, I prefer as little distraction as possible from the subject. So your minimalistic approach is wise.

I'll see if I can find some good resources for themes/templates.
