Heliconia watercolor painting

I started another painting last night of a beautiful Heliconia.  Lots of details still needs to be done on it but as you can see, it has lots of different color on the flower itself.  I have a problem of whether to finish this painting in a light or dark background since the value of the edges varies from very light to very dark.  This photo shows that I am trying to use a background variation between light and dark values.  It might work but I think in some areas it can use a bit darker value to make the Heliconia stand out.  I will work on it more and publish the finish work on a later date.
