There’s not much I can say without advising you to scrap the whole system and go CCBS. Some pointers would be to remove - or to add more of, if you’re so inclined - the black armor, maybe replace some of the random sockets with more CCBS armor if you choose the latter path. Maybe remove the the extra spikes on the ankles and the claws, he’s got enough edge without them. Torso would probably stand some actual armor. Lastly, simple fix for the busing on the back - add a gear there.
First impressions: the black CCBS shells grab my eye, and not in a good way. they clash with the rest of the rest of the heavily greebled textures. move down a bit, and you come to the knees’ open ball joint. it looks gappy, and it’s a eye sore. on the other hand, the chest is cool, and the color scheme is very nice and menacing.
Closer Look No.1: from what I see, it looks like the arm can’t move much back and forth. I’m not a fan of the different blade pieces being used for the wings, but that’s subjective. I’m not sure what to think about the feet. one half of me says there isn’t enough “feet”, while the other half says, Look at those talons! as for the hands, imo they’re not that good, mostly because of lack of finger articulation. And the coloured parts. the Purist says kill them with fire, while my rational side says, “these are really cool, and they’re not my bricks, so I don’t care as much. I’m still not painting my bricks though.”
Note assume that I like everything that I didn’t comment on.
It’s ok, not good, but ok. Essentially being an Inika build, I can’t say too much about new designs or anything. Also, you made him really hollowed out, giving him a sloppy or incomplete look to him. Maybe try out a bit of custom, and then see what you can come up with. Usually by V3 with a self MOC they are nearly completely custom, or else seeming lazy. And I do agree with @Hawkflight about CCBS. I feel like it would give him a better overall appearance and look more clean as a whole.
