I managed to get around to doing his trousers today:
Layer 2: Codex Grey
Layer 3: Codex Grey with white added
Layer 4: Codex Grey with even more white added.
I think the contrast between Codex Grey (the deep shadows) and layer 3 is a bit too much; I think I'll mix a shade in between next time I 'm doing grey.
Shoes are basecoated Ushabti Bone, which seem awfully yellowish, but I hope I can work it up to a non-greyish white to look a bit like the sneakers he's wearing in Temple of Doom.
I overdid the painting on of folds a bit; I have a tendency to make the darker areas too narrow, leaving too little space for the lighter shades. It's a matter of practice, I guess...
