Hi
right now I can't really tell you about your theme, because I'm working on bad monitor, but I can give you some thoughts.

Everyone has their own opinion about blogging and blog themes.
You will find some people like a tight blog with few ads for more impact.
You will find some folks enjoy the most techie type blog for that wow factor.
You will find creativity is just the beginning. It depends on your target audience, your own design tastes, and you'll keep tweaking and tweaking its addictive!

If it was me I'd check out the competition
find out what type of blog format they are using and then compare it to my own. See if you think they have any ideas you aren't using and improve upon a good idea.

Just my 2cents
