This is an original art card. My cat Juliet is the subject and I added the balloon to give her something to look at. This is watercolor (with touches of colored pencil & ink) on 140 lb. hot press paper.
Here's another rose art card (2.5 x 3.5). I used a limited palette of rose madder, cobalt blue and new gamboge to paint the rose with a little alizarin crimson and ultramarine blue to paint the very dark crevices. The background is mostly sap green with a little burnt umber and winsor green and a wash of cobalt blue. This Ebay auction is starting at .99 with no reserve.
