Nanjing Butterflies

This painting will be auctioned for Hopeful Hearts a charity group here in Nanjing that raises money for children who have heart defects to have operations to save their lives.
The yellow in the painting represents Hope. The Plum blossoms are formed with small heart shaped petals. The plum blossom is the floral emblem of Nanjing. The butterflies represent the "butterfly children" from the Hopeful Hearts website.
It is at the framers now and is being framed with a cream matte with a small red stripe and a black frame - it was difficult to negotiate anything else with my limited Chinese skills!
Postscript: Here is the digitised version. You will see the changes that occur to colour and lines when the paiting is transformed to a vector design.
