Improv Flowers for Bramble Blooms (or Not)?

These are big flowers on a background that measures 21" x 28".  Mostly that size because I make bed-sized quilts.

This is an unfinished center--nothing is stitched except the green stems to the bases of the flowers.  But I'm not sure they're really improv-style flowers.  What do you think?  The improv flowers I've seen on quilts seem to be more static and stylized than these.

Notes on unfinished parts of the center. 

• The white in the center at the base of the flower is white paper pinned as a place-holder for either another shade of green or some other color.  (What shade of green or what color?)  Or don't add them at all?
  
• The little dots under one side of each of the flowers--brown paper affixed with halved adhesive circles--were in my original drawing except on both sides of the stem.  They don't have any significance, but I like the idea even though they're more decorative than anything else.  But then there's the color....
  
• The vase shape and size are yet to be determined (if I continue with these flowers).  Wider?  Shorter?  Color?
  

I really like the flowers.  In fact, I love the flowers.  I'm just uncertain about their being at the center of an improv quilt.  I don't know what's coming next for the first border and subsequent borders so I don't know how that will impact this center.

If I continue with these flowers, to your eye what looks settled and what doesn't?  What's missing?  Do they need leaves?  Do they need rearranged?  What about the empty spaces on either side of the container that holds the stems?  Too bare?  (I know I can always add later.)  Should there not be a container and, if so, what color?  Is the background too big?  Are the flowers too big?  Are there too many, or too few, flowers?  Would one be enough?   (You can see my first idea for a layout at this post if you scroll down a little.)  I'm really out of my element with making a quilt guided by someone else but I'm also finding the challenge worthwhile.

Here are close-ups of the individual flowers, left, center, then right.  I do really love them and if I don't use them for this quilt they will definitely appear in some future quilt.

As I understand it, improv is both a style of quilt and a process for making a quilt.  Does it matter in the end whether a quilt looks like the usual improv quilts we see?  It probably matters more that it looks like a finished, complete quilt, and that all the parts and pieces belong where they are.  Perhaps process is more important than style?

I would love to hear your thoughts and opinions about these flowers as a center block for Audrey's Bramble Blooms 1 improv quilt-along.  Even if comments are somewhat critical or negative but kindly stated, I'd like to read them.

Big thanks to Audrey of Quilty Folk who is hosting this quilt-along.  I know it must take her lots of time to plan and write the posts for us.  Find links to others who are participating in the sidebar of her blog.  (There are now 34 of us!)  And big thanks to you, dear readers, especially you who leave comments and thoughts.
