OK, I've had an initial look at it. I didn't put the into the game yet, because due to the progressing patch work, mod files are not suitable for new file addition at the moment, but I've gone through the files, they look quite interesting. I put the OGFs into the MAYA and checked them as well. The Skull and the Wheel have been included. Actually, particularly, this Skull is a rather in-genius idea as an artifact. It needs to be associated with a story for it. Text file can be directed to Eng Text file and written a couple of lines foe the explanation and story such. Very good work.
I hope that I'll be able to run them in action during weekend (I'll put another gamedata NEWSA v3.0 and run them in it)
You can create more styles along this path, you've got grabbed the know-how and the vision for it.
I think your work will nicely fit into NEWSA, into the coming Xtreme++ (coming after this imminent patch)
