I had some space to concentrate today, so I worked on this a bit. The background is nearly done and I've started modeling the pepper and working on layering the color.
The good news for me is that the cp's layer beautifully over the markers, actually better than over the Neocolor II's, about the same coverage as Inktense. The markers, however, are much more brilliant and go on more smoothly (remember I am not a watercolor person).
I'm very excited about this experiment with the markers and will be researching the lightfast qualities of different brands.
