Putting the poem on the back is something I hadn't thought of, but I think it works well.
Note to KR: You have opened up a whole new line of thinking about these card designs. This is the first one you asked for. I didn't use a frame with this one. Without the frame, it maximizes the size of the mandala. One with the frame is coming next.
REFERENCE: i36A, t1, v1
Labeling these gets more complicated as I generate more versions of the images, so I am initiating two new refinements with this post. I am calling this version of the nightblooming mandala with the rows of flowers on top and bottom "A". Also this version with the text on the back without frame will be "v" for version 1.
