Large Loose Floral in Acrylic WIP

I am still working on this one. I started big, bold and splashy and now I am stymied. I always had in mind to layer a lot of different colours, especially in the background.

I utilized a lot of tools and textures in this painting - bubble wrap, drips, spatulas, spray bottles and more!

My reference was actually a stock photo with a white background so I have in mind to layer white over all the blue as I am not sure about the blue background. I think a lighter value would be more effective. What do you think? Please let me know if you have an opinion as I am frozen with indecision on this one.

It is a large painting of roses and tulips on a gallery wrap canvas - 42" x 42"
