Hey Sam,
I am little confused what your site is aimed about as your post description wasn't very extensive.
I am guessing that it is self explanatory 'fings' by meaning anything that catches your eye and fancy writing about in your spare time. I like the layout and after reading through I am Legend you are obviously a talented writer for 12 years old.
I can't say I like the Snapshot feature when hovering over hyperlinks.
I reccomend you make your blog feed visible to get a good flow of traffic
Here are some buttons to make it look visually attracting:

You are doing a good job with the tags, lots of bloggers always forget to put labels or tags on there post as they think it is not neccasary but I think its an essential when blogging to help people find what they are looking for.
Great site and keep it up.
