errm i don’t know it looks compact the waist looks like a big block, the shoulders are skinny and there might need some red in the skirt some pictures without the weapons the cross and the skirt might change how i feel.
with the skirt i feel like you just got the thornax launcher parts and placed them on there, although it is a good idea to use up a part that most MOCests live to forget i just dont get a skirt vibe from using them.
the colour choices is great but there could be more red like the small red tooth pieces for the back of the leg it is bare there (just an opinion) the blue pins are the elephant in the room and the tan 3/4 pins dont suit the moc in my eyes but if you do have loads of them then its good to use them.
is it possible you could add two more skull spider silver masks in the shoulders facing sideways just to fill out that space.
the using of the 2015 and 2004 toa skulls is a good idea to be like trophies but i’m not sure about the Noir (Noir is french for black) Phantom helmet.
i would like to see this moc in more poses because with the pics you uploaded gives me the thought that he doesn’t have much articulation
