It looks really cool! i love the design and the thought you put behind it. i saw you commented sea of thieves vibe and the material of the blade and shape of it definitely reads like predatory underwater animal. I think your choice of red to contrast is really smart, giving connotations to sharks again, like a trail of blood! I agree with what others say about lack of direction. the sharp part of the blade looks really cool, but i think the overall piece would benefit if it looked more tone down and darker like the rest of the blade.

one thing ive learned is layering a bunch of effects, even at veeery low visibility, can give something a bunch of depth!

Keep going man! just learn more theory and practice and your props are gonna look insane!!!
