Layout wise, it's pretty standard and is a commonly used one these days by quite a lot of people.
Type wise, there's some bits that are niggling away at me, but I might be a bit too picky..
You've quite a mix of typefaces on there in the banner at various sizes, which is a general nono from me anyway, but a few more specific bits;
1. The pt size on 'MY NAME IS' and 'I DESIGN BEAUTIFUL' are a pretty big difference, which looks a bit sloppy to me and like you've tried to cram it into a certain size.
2. The distance between 'HELLO' and 'MY NAME IS' is a few pixels more than between 'MY NAME IS' and 'I DESIGN BEAUTIFUL', something which niggles me again as I can see it naturally.
3. The kerning on 'FOR HIRE' is what is niggling the most though as it's too tight. With a Sans Serif typeface, especially in capitals, it's pretty vital to get it right and at that weight it looks odd.
The I and H are nearly touching, and the I and R are then a different gap apart, and in general it's a bit out.
The text below starting with 'From a redesign to a whole' is also really close to the bottom of the available for hire bit, if you drop that down it'd look more clean, as it's almost touching at the mo.
There's also things like on the 'ABOUT ME' part;
I'd drop Skillset down so the top of the S is in line with the black line on the right.
This would also I think solve the next part -
Skillset and the list are on finishing a 'line' above the services and info on the right.
If you drop the Skillset down, it should then all be in line and look much tidier.
The skillset also looks too tight to the information above it so dropping it down would solve that too.
These are pretty picky things, but it just looks a bit untidy in places, and when I've worked doing bits for web from the seniors I was with I'd always be picked up on little bits like this, and when you see the before and after it really does make a difference.
Of course, this is all by eye so I might be slightly out with a few bits, but have a fiddle!
On the navigation - I really like that. I was wanting to build a portfolio site with the same sort of navigation a while back, but i'm terrible with code so just didn't get to it.
Like it a lot though.
A slight concern I had with it when I was thinking is when the 'Portfolio' section becomes quite full.
I think when I was doing it about 6 'blocks' as such was the max where it looked good, I think 9 was too much when I was doing it.
That's just a concern as and when you come to it though, I'd imagine.
Strong choice of colours and I quite like your Logo thing, like the roughness of it.
Overall it's pretty good, just the niggles and then it'd be sorted I reckon!
Sorry if it's a bit too picky, I do like it though! I've attempted to put bits in bold that are important to break it up!
