I used the Prismacolor colored pencils on the three flowers too. I figured if I used them on the purple one I had better use them on the other two a little two or they might look funny. Here is what they look like now and the way they looked before. New photos with the shading done are on the right. The pink and teal don't have much change but in person they look a little more shaded on the tips. The lighting was a little different on the photos too so it really isn't a very good comparison. I used a light pencil and shaded a little to the inside of the petals too. As you can see the purple one has the biggest change. Not sure this is the final look but sure is better than the way they were at first.
Now on to the binding.
