I need some cosplay help!

[Blender]

So I'm going to cosplay as a Shadow Heartless from Kingdom Hearts and I have the base for my outfit.
The sentai suit covers my whole body toe to the tippy top of my head but I need to figure out how I should make the feet and hands and how to attach the antenae and eyes.
Help please!

I also want to cosplay Dr. Kevin from the game Puchi Puchi Virus but I can't find anything for him anywhere.

It's be nice to have a ref for the Shadow Heartless. I only vaguely remember what those look like.

I think it should be pretty simple if you get some stretchy, hose-like material, cut some plastic sheeting or foam into points, and stuff the hose with those shapes. then, for the antennae, just stitch them to the top of the suit. For the hands, likewise. Plastic sheeting can easily be cut and glued into points for the fingers, which could be put into stretchy gloves or something similar. Same with feet, I would think.

Anyway, best of luck!
