hmm, took a look. I like the colors and all, you could widen your one column if you like, it takes up about at third of my screen, there's a whole lot of dead space around it. It lookslike you have all the latest and greatest toys going already. Personally, I would make more differentiation between your bottom bar, where the feeds and everything are, it kinda bleeds from articles right into that stuff and I didn't notice. Make sure you have you settings the way you want them so your bottom bar doesn't run away as you add posts.
Your left most top colum of links is overlapping part of your middle column.Your feed burner icon at the bottom is overlapping some text, I assume that is a CSS postition (absolute) type issue.
For personal taste things, I would just use one or two feed buttons. Blog roll is nice, flickr - eh. your feeds within your blog are easy to just space out past, some color change would be nice there and maybe shorten the text, it's a lot of grey to wiz past.
that's it for my nontechnical newbie ish eye.
