I was feeling graphic tonight so I took a hosta leaf and did a good old fashioned flip. I added Pro-contrast & Solarize from Nik Color Efex after the flip.
Powerful graphic abstract, Julie. I might be tempted to soften or clone the horizontal light line on the left and right center as it seems this remnant of the flip edge is the only straight line in the image. Your filter combo/flip really sets this Hosta leaf off!
