I like it. In fact this is how my first idea looked like, but later I changed it because it was not evil enough as someone pointed out to me. I'm going to make my Vader/Predator much more evil Sith, dark inspiration.
You should draw out a concept, i'd love to see it! Maybe after you do I'll do a piece of the two clashing in a "bad Blood" nod.
ROFL, okay now ive definitely seen it all.
