Eastern Spinebill, Banksia

I've been playing with watercolours a lot lately, I think this is my best effort so far. Hope to have more to post soon, and a better camera to photograph them with this one is pretty ick.

Well, I'm trying to decide if this is best left as is, or if I should do a background wash in blue-grey. Any advice will be welcome

Oh and hugs, I've missed posting, and sorry I've not been more active. Real life has been a bitch this last year.
