Sci-fi Frozen Sword

Hello everyone,
I published my first sci-fi model few days ago, and I'm planning
to create more weapons of this style.

I started creating 3D models five or six months ago, and
I know that I need more experiences and techniques, so I would like to
listen to more experienced artists' advice.

I will really appreciate if you could give your opinion about my model and
it's price.

Thank you in advance for your great tips!
