Honest opinion... start over, that 8bit design is really hard to read and honestly made me want to leave the site. Also as much as it's kind of trendy to be 8bit at the moment it's also kind of feels dated, especially to non tech/trendy people who might not be aware of the returning popularity of 8bit games.
I don't actually know what your site is for... you've got a great big contact button but I have no idea why I would actually want to contact you.
There are consistency issues with things like sizes of boxes on the timeline as well.
Nintendo have also been pretty hot of late over people using their 'products' without consent so your mario and pokemon might be an issue, not to mention looks quite 'immature' to me personally.
Why have you got links to sites you like, this is a portfolio/cv/resume type site so they aren't needed. You also need to put more emphasis on any 'portfolio' work that you have.
It's great having a little personality on your site but ultimately you're trying to sell yourself as a professional and imo some of your likes kind of makes you look like you're a little immature and/or have the wrong priorities.... I'll be blunt, if I saw your site I wouldn't hire you because you don't seem to be that serious about 'work'.
In my opinion, if you're someone who is basically teaching IT and web design etc, then imo you should really be showing off what you can do and to me this just doesn't really do any of that.
