Thanks for your comments, all!

It depends on what mini and how complex it is, what colours I use (if I use colours I\'m very used to and don\'t need any experimenting), and if things generally go my way. This mini is complex and I tried lots of new things on it so it took quite a long time. I\'d say a bit over 30 hours. Other minis may take 15 hours or even 5-10 hours.

I don\'t know if it is limited or not, but it\'s not available for general sale. It was available at a show in Paris, and possibly it will be available again at other events. Don\'t know.

I like both backgrounds. But, this one turned out a little bit more blue than I intended. The printed background is more towards the green. And it makes the colours of the mini stand out better.
