Hi Chris,
A few thoughts:
I found the diagonal background a little distracting, might be better to have a solid colour behind the content. Just makes the content wrestle with the background too much for me.
It's all a little neutral as well, maybe it needs a little colour to liven it up a bit.
I think you're going to have to be careful how you lay out the content as well, I know it's early days but the mock up you have is a little blocky.
Also I almost got knocked out by your blog header, it's massive and felt like a blow to the head when it loaded.
There is no message to your front page either, just a short description and straight to the content. What do you want/need to tell people as a first impression
On the plus side the logo is simple and strong, most of the site colours are complimentary to it (still think you need a highlight colour though to breathe a bit of excitement into it). Using a serif font for the main header, so close to your modern looking logo is confusing too, sends a mixed style message.
Sorry if this is too much, hope some of it helps.
