That's actually a really good point. I'd brushed over it. 

Much appreciated, thanks o/ I edited, hopefully to be a bit better.

The AA colour is too similar to the main colour, so it doesn't help reduce the blockiness. Where you use it for shininess in the text, it's not even noticeable until one looks closely. I recommend using a darker colour, something a little closer to being halfway between the light grey and the lighter blue-green.
