Local colour picking
I spend some time tightening up key shapes. One tip to remember is to stick to the colours that are already present in the loose sketch. I use the Mac’s Option key to quickly switch to the Color Picker tool, enabling me to quickly select local colours that I’ve already defined, and then can paint with smaller brushes to tighten up shapes.
I continue to tighten and refine the image and explore how the clouds might layer in the peaks. When I say tighten, I mean zooming in and painting cleaner edges and finding the final shapes and details. I only use the colours that I’ve already determined.
