messing around with my blog

I am tinkering with my blog design. It seems more complicated than it should. I am intending to add some pages of art that I will group into common subjects as I have posted on them. And I am playing around with various headers to add some punch to the page. So, this one?

Or, this one?

How about the one I already inserted into the design above? I am using that one in my website already.
I am not happy with the design yet, I will have to mess around some more.
