The glowmap looks FS1 Shivanesqe
Yeah, it hearkens back to those fond days where Shivans ships had simple paintjobs/textures.
To make some general comments, I like the simplistic style of this Sath. It's consistent, ragged, scaly, and like others have mentioned, looks a lot more evil. Whilst Rga's says "Get near me and I will **** you up with my uber lazorz and flax and sup3rnova cannonz", this one is more "Get near me, and you'll regret it. I won't tell you what I'll do, but you're not going to like it". It looks menacing without looking like it bristles with firepower (even though it does). Just keep doing what you're doing, bobbtmann. I know it'll turn out brilliant.
