I started with the Astaroth (retail, since I'm pretty sure there is no high-poly version, and if there was it would mean more work for me).
Well, no... I startedx with what was meant to be a Rakshasa/Lilith/Aeolus hybrid, with parts from Isises, Beses, and Astaroths stuck on in various places. But obviously that didn't turn out very well.
So I took two Astaroths and put them intersecting each other, and connected faces and stuff until I felt it looked good. And then I made some tweaks after I had finished merging them into a single object.
The uv looks like crap because ... well, that's sort of what happens after you make tons of edits with no texture visible, and then you realize that the only reason a texture isn't displaying is because you never told the program what texture to use for what material. So there are all these stretched out things and crazy shapes on the uv map that make no sense at all. I tried to 'repair' it starting with the easiest-looking part, the top of the nose. But it didn't turn out. So I made a bunch of untextured renders (
some smooth,
one with auto-smooth), and a
video that manages to hide some of the texture woes with compression artifacts.
The name "Astaroth 2.0" is just a placeholder. I looked on Wikipedia for something related to the name Astaroth that might be useful, but was too lazy to read the whole damn article.
