About this 3D model

I'm still a beginner at 3D modeling, but I gave it my all trying to think of another design for the Brachydios Insect Glaive. I actually had to look at the monster and decide which parts of his body would fit as a part of the weapon. The base of the rod is meant to look like Brachydios' tail, while the blade part is based on the head. And the reason I chose this weapon was because I was never fond of the actual weapon in the game (which looks like a toothpick). P.S.: I didn't print this model, but instead took renders of it.
