High- and Lowlighted Floral Images

I started out with Donna Mikasa’s idea of “water painting” from Day 6 of Stretch Your Stamps 2, and ended up with this variation that has both highlighted areas and lowlighted details:

I stamped the image and sentiment from the “Peaceful Petals” set from Stampin’ Up (now retired) with Versamark ink on some watercolor paper, then added white embossing powder and heat-set it.  Then I sponged Seedless Preserves, Broken China, and Peacock Feathers Distress Inks over the entire panel using an ink blending tool.
Using a Faber-Castell waterbrush, I removed the ink from inside the image borders by brushing on a little water and dabbing with a dry babywipe, leaving a pretty bleached image.  I wanted to take the technique a little further, though, so I added lowlights to the flowers with a blue-violet water-based brush marker. 
After spattering some water droplets over the entire piece, I mounted the panel on top of some dark navy cardstock (source unknown…came in SSS card kit though, so probably Bazzill?) and then onto a white cardbase.  I’d love to hear your comments!
