I have too much faith in humanity to believe that your current website represents you, if it did you wouldn't have had enough of a sense of humour to chuckle at the graphic! The issue isn't with your site looking more formal than informal, as you say, if you're quite a formal guy then naturally your site should be formal. What I suppose I'm trying to get at by calling your site 'corporate', is that it doesn't really convey any sense of you as an individual, it's more like looking at a less polished version of the Halliburton site. (< Not a good thing!)
 
Take this guy's site for example:
http://www.alittlebitofsomething.co.uk/
 
This guys page has been used by others on here as an example in the past, but it's a good example of a personal site because you know exactly what to expect by ordering a site from this guy. i.e. It's likely to be a creatively designed site, you have a good idea of cost, as a client you know your place in relation to the designer, and the guys personality comes across in bucket-loads.
 
I'm not proposing that you copy this guys site, that would be ridiculous, I'm just proposing that you take from it the importance of selling the self-employed persons sole asset - themselves. How you wish to present yourself is the determining factor in how your site should be designed, take your question for instance:
 
 
Every type of font, whether it be serif, or sans serif or script says something about you. Generally speaking, a serif font says 'traditional' and a sans-serif font says 'modern'. If you want your site to look more soft and appealing, yet at the same time formal, then you're really crying out for a serif font, but because your accompanying text is quite small, with your current design you'd probably need to restrict the serif to headers and use sans-serif for the paragraphs. That restricts your choices quite considerably because in order to 'match' a serif and a sans-serif font they can't (at least with your objectives) be very different from each other. That means you've not got a whole lot of choice but going for something like Georgia for headers & Arial for text if you're restricting yourself to web-safe fonts. (There are dozens of other combinations of course using @fontface, but even then you don't really have the option of using a really 'mellow' serif font on your site because of the layout.)
