Well, very well done! that is a cute one.
As you know, these are native to us here in Australia, along with many others. It is funny to see them being grown worlwide. Here, they are treated like dirt by most gardeners and most of these are mounted on trees and tree fern logs and slabs and left outside year round with hardly a look in until they flower....
Mind you, with a little care they can be beautiful things such as yours.
The trick with these guys is to keep them fairly dry and bright in winter, with minimal or no food at that time. We have ours on the forks of trees and on rock crevices in the garden and still they bloom their heads off every spring and summer.
Congratulations and hope you will try some more Aussie natives. I think you should try Den. speciosum var hillii or as it is also known these days Den. tarberii.
Cheers
