A few months back a friend of mine was looking for books on mandalas and how to draw them. I remember that at the time I wasn't particularly interested in them. I didn't really know what they were.
After my first attempt (above) I completely understand the whole, "draw it carefully" statement. If you're not careful, the motifs would end up all over the place, and the mandala would become uneven.
In my next mandala I hope to incorporate more empty space as part of the design.
