Hey, great start!
I'd run all my language through a spell-checker. Unless "interests" is spelled differently on your side of the pond, that's a typo. I think I also spotted a sort-of run on sentence.
On https://gotsocial.co.uk/colours/index.php in Chrome, the green buttons don't seem to be in alignment. I kind of assumed they were supposed to be centered, looking at it (I didn't inspect the code).
In the "My Projects" area, I'd make the titles under the photos also be links. You can style them however you want, but I think some people would expect to click the words and be taken to the appropriate project page.
I wonder about using anchors for things like instructional popups. That gets saved into the browser history, and then if I use the BACK button in the browser the popup comes up again ... not what one expects.
