Intricate mandala to color

This mandala is one I started 3 days ago. Then decided I didn't like the center, and it took a long time to color even doing it digitally. Then after I had the colored version just done, it wasn't just right. So I had to recolor it. I do like the color wheel effect now that it's done! This is for the people who really love intricate designs and have very sharp pencils or fine tipped pens!
