I quite like that, a few things though;

- I think the date thing looks a bit strange, i'd seperate the header from the date / post title box.

- I'd make the older posts that are just listed a bit more visible, like maybe add a smaller calendar date thing next to each of the titles.

- I think currently the side navigation boxes on the side look like they were originally white or at least a brighter colour and you've just lowered the opacity down on them. I'd personally make them a lot more visible, possibly even white.

Nothing else to say really, your current style you seem to be designing with is a big improvement on how you used to design.
