Bird Panel Finished I Think

Okay,  here is what I have done so far........    I'm not sure if I should fill in the blue area around the birds and leaves.   If I fill in the background what would I use for a fill???????    Do I want a combination of fills or do I want straight lines to set off the pebbles,  or sun rays,   or   hummmmmmmmmm! 

                                    All the fruit, leaves and birds are outline which gives definition........ 

I just don't want to over quilt and have to pick out stitches.....

Guess I will sleep on it ........
