Website I have been developing

Here is a website I have been working on as part of an assesment I got at the moment.
http://www.arctosdesign.com/blog
Its really the first blog I have ever made and also the first css page I have ever made so all round it has been an adventurous learning experience. I realise that on slower machines the background image and maybe some of the others may take along time to Load… Sorry about that I still have a few kinks to iron of and that is one of them which will happen in time aswell as the portfoilo section still needs to be styled so at the moment everything in there is more just a space waster so I atleast have the page and can think about where to go. But please feel free to critique. Oh also the coments also still in style mode so any sugestions would be cool on what I could do with that otherwise don’t strees the fact they look naff.
