Birds of a Feather

Not sure what to do with this one - part of me thinks I should leave it alone, but then again, it's a lot of empty space. I'm toying with the idea of a birdy collage in the top left, but that's a bit obvious, isn't it? Or I could glue seeds somewhere... Really don't know. It all started with 2 acrylics blues and plenty of acrylics glazing medium (matte and glossy), and a fan brush. Nothing more than that. Then I decided to try and glue a feather to it (used the Liquitex gloss glazing medium, excellent glue). And I like it just like that. But the question is "Is it enough?". I'm not even going to ask the obvious question!
