I have just completed the Parliament Building Carving I. It's only 7.5" x 7.5' approx. on Fabriano Artistico SP. I went for a sun-drenched look contrasting with shadows in the recessed areas where I created a lot of textures.
I will have to live with it for a few days before I can decide if i like it enough to continue with my intended series of such carvings.
