Spent today working on the cast shadow of the vase. I started out using the #2 & 3 FC Polychromos Warm Greys to fill in most of the areas, then I went in with Warm & cool greys #4 & 5 to fill in the darker areas leaving all edges soft. Then I went in with my battery operated eraser & took out areas of light especially the lightest down to the white of the paper. Added in some brilliant blue for the prism marks ever so slightly just to influence the reflections from the sunlight hitting the crystal. And that’s it! Hope you like it. Any questions feel free to email me. I’ve added all 8 stages so you can see the difference side by side through my progression.
