Starting off, I pin Thagrosh as I do with all my large models and pose him, then fill all the gaps with green stuff. Because of the requirements of this project, I then cut off all his spikes and start replacing them with crystal. I do some rudimentary green-stuffing to blend the crystal in to his skin, but I'm not super happy with it. You'll notice by the end, it's much more different.









I wanted to copy the appearance of the amethyst crystals, but with a colour that would stand out from his skin. I end up going with a dark / beige look I've used often before but paint in a lot of lines along the curvature of the chitin.





For the crystal look, I go with gloss again. From the middle to right pics is the difference between one and many layers of gloss. You can see with a first layer of a surface like this, the gloss pools and stands out between the plates. It takes a bunch of layers to make this look uniform.













And finally, here we have Epic Thagrosh in all his glory!
