The refine edge and paint the selection!

The refine edge and paint the selection! - student project

For me the paint the selection and refine edge were the revelations! But the whole 10 minutes were great overview of what I already know and what I didn*t knew yet! Like the oval selection, I now finally know how to place it :-D!

However I try my best on this picture and can't get it right ... I want to mask all aroung mandala yet keep the black dots - can you advice me what to use?

I tried quick selection and refine edge, but that made it edge half transparent, my best try was magical want on the white around and I am thinking on hand painting the mask around the dots. But maybe (I still hope :-) ) there is an easy way to do it?
