Hydrangea WIP (work in progress)

One of my favorite flowers, and much beloved by all. This delicate beauty, looks wonderful on the bush, and stands up as a lovely dried flower, in many vases over the years.
I wanted to get into the world inside this flower, one of the few that gives us a true blue color.
I consider this painting a study, for a much larger one I wish to do.
This one is for an artists monthly event at WetCanvas Florals forum.
Not quite finished, as I need to do my shadows, and highlights yet, and post it later today at WetCanvas. But wanted to see if there were any other fixes needed first, and they seem to show up better posted here...........
