As I neared the end of the process I was sensing that the pigment on the paper was very close to turning to 'mud'. Parts of it were feeling a little over worked and other parts where losing their luminosity. I think one more glaze would have been a step too far. My guess is that some of the pigments I used lacked sufficient transparency but I'm also thinking that maybe I mixed some glazes a little too dense. I think that more water and a better understanding of transparent pigments would help a great deal.
Still, I'm not disappointed in the result and it was great to be holding a paintbrush again. And I'd love to hear any tips from all you competent exponents of glazing out there.
