Portfolio - I agree with Yaustar. I don't think a blog should be used to show your portfolio work. It seems less professional in my opinion. There are plenty of wysiwyg websites that require no knowledge of scripting to create a site e.g. www.freewebs.com
I would get better quality videos as this is the easiest and quickest things that a recruiter will look at to judge your skill and if the video is not clear enough to showcase your talent you could be overlooked as a potential candidate for a junior design role.
Also, maybe include links to detailed documents showing your thoughts behind the making of your levels i.e. gameflow, story behind map, setting, inspiration, reasons why you made it etc and maybe (as the video is not very clear) a top down map. I like the level of detail you put into your challenges posts. I know that this is required when you enter but this is the sort of detail that I would expect from a document supporting your level design.
Also, it seems that your portfolio is not clearly aimed at where you want to be within the industry as you have got a lot of content. Do you want to be a games designer, level designer or character designer? I know in some companies these roles are often taken on by one person however it should be clear where you want to end up by your portfolio content.
CV - This is just my opinion, but I think you should swap DD to Distiniction in against your most recent educational institution. When I see a DD I automatically think this is a low grade, simply putting the Distinction should suffice. I'd also put your university instition first here as this shows immediately that you are studying at university and in a games related course. Whether you have completed this or not is besides the point. Put 2008 - present this is usually the case of most undergrads looking for a graduate position.
Lastly, you should only need maximum 3 referals on your CV, 1 personal and 2 professional (previous and current) so I would cut one out.
Hope this helps. Best of luck with the portfolio and your degree.
