While what you say is true, the reality is that it looks like something that already exists and is well known in the community. It’s impossible to know about everything else that’s out there when you make your own design choices, and while there’s theoretically infinite variation in what’s possible, sometimes things just happen to look similar. Bad luck strikes us all there.
If you want me to judge it just on the MOC itself, I’m afraid I don’t like it. The chest and shoulder construction is quite elegant, but the arms and legs are simply setlike and uninspired. I can’t see what reasoning there is behind the asymmetrical shoulder armouring either, and the left leaves the messy balljoint area exposed. I’m not a fan of the head design at all either. It’s boxy and has a + shaped eye and what looks like a gaping, open mouth as well.
The proportions are quite strange as well - it suffers from having very long arms and comparatively shorter legs like the G1 sets do, which unless that’s what you’re going for is something most people on here try to avoid.
And why is there only dark red on the upper arms? It worked well on Telya because it looked like epaulettes, but here it seems a lot more out of place.
