Well, I put some more time into Glaun. First off, I did the inside of the mouth, gums, and exposed musculature in purples highlighted up to pink.

Posed with some light in his mouth, so you can see the detailing of the floor.

It looks very odd now, but that's because of the contrast to the black teeth. As those get painted, it'll look more natural.
I then base coated the rest of the model - scales, teeth, claws, and the underbelly. I'm painting all of them the same color, and I will then glaze the underbelly to give it a more green tint to bring it back into the skin tone.

The first layer is 4 parts Leather Brown to 4 parts SS Camo Black Brown to one part Goblin Green, which if you remember, was the midtone for his skin.

Though not obvious, using a touch of that goblin green will blend the two shades together and make them seem more natural next to each other.

SS Camo Black Brown is one of the utility colors I use very frequently. Any time I want to make something darker without using pure black, Camo Black Brown is what I use. It adds an earthy realism to darker colors, and allows me to shade several vastly different color schemes will still pointing them to similar points of the spectrum.

From underneath, you can see some of the brown in place on the underbelly.
I let it sit overnight (unboxing the trolls took longer than i had expected), and came back to it the next day.

The second layer was 4 parts Cobra Leather to 2 parts SS Camo Black Brown, with 1 part goblin green for consistency.

The scales took longer than expected - there's a lot of detail there! You can see the brown already becoming brighter. We'll continue that trend...

The horns are being done the same way, but figuring out how to use the ridges effectively on the top set has been a challenge so far. Also, my IPA went empty and had to be replaced.
Layer 3:

Refilled with a Flemish Sour Ale and went back to work. This time the color mix was simple: 4 Cobra Leather to one Goblin Green.

You can start to see the highlights coming in. With the green additive I've been using, the scales look like they belong, instead of being completely apart from the skin tone.

I decided to shade the bottom horns as I normally would, but to allow the rings on the top set to break up the transition from light to dark. At this point, it's still too early to tell if it will work.
Layer 4:

The fourth layer showed 2 parts Cobra Leather to two parts Medium Grey and 1 part Goblin Green. I also switched from a Games & Gears 1, back to my Winsor Newtons.

The scales are giving me more trouble than I want. There's an intricate balance I have to strike between correctly shading each scale as its own entity, and shading the back of the model as a whole. Some scales are just being highlighted at the tips, while some are being highlighted at 50% of their surface. I felt good about where they were last night, but looking again this morning reminds me I'm going to have to pay close attention to this.

The horns on top, however, are coming along better than I had expected.

Lest I forget, work is still being done on the underbelly as well. However, it had become 2 AM, the beer had run out, and work beckoned less than four hours away...
