California State Bird and Flower Color Version -WIP6

In my last post I showed a detail of how I was blocking in and blending the oranges and yellows of the golden poppies of my CA state bird and flower artwork. Here is the end result, with all the flowers colored in and blended.

It's almost done! But there's one more important thing I need to do. No, it's not filling in the background. I'm leaving the background plain ... transparent actually ... so I can use this image on things where you wouldn't necessarily want a background, like on t-shirts. So what is it I need to do? I show you in my next update!
