I went to your website and the pictures there are much better. You should have posted those instead the one we see here.
Having seen them close up I'd say the minis are a 7,5, perhaps 8.
There's nothing wrong with the photograph, you've just squeezed too many images into one montage. If my initial comment didn't sink in, I'll repeat myself: The site limits your image width to 600 pixels. Repost with that in mind, there's no point asking us for constructive comment if we can't see anything!
