It's really quickly sketched, but the triangular leaves are just interesting. It's an Oxalis Triangularis (known I guess as the common name Purple Shamrock). I think this sketch captures some of the energy and the lightness of the plant.
The prints are really nice.
The original 6.5" x 9.5" drawing is from my sketchbook, and the prints are so accurate, you can just make out the drawing on the backside of the paper. I print using pigment based ink on a high-end Epson printer on Hahnemuhle German Etching paper. I print on 8.5" x 11" paper and leave a border, so these are really easy to frame. Each print is signed and numbered.
