this feels so awkward

Let me tell you, I think this is absolutely excellent. I love the animation you're doing. It's very expressive. You're able to display emotions very effectively with these 3D models.

However, if there are people who are telling you this feels unfinished, or it needs work, I would disagree with them. This is an excellent storyboard for an anime. If that is how you contextualize it, it's amazing and I love it. If you didn't know, there are a few anime that utilize 3D models in a manner just like this as a method of storyboarding. I think Attack on Titan did it that way.

This has a lot more that could be done to it as a 3D animated series. However, I have no doubt that all the improvements you could and should make in that realm would *multiply* production time. Models need to have precise weight-painting in the face to properly display the emotions you are expressing in close-ups. You need to create a new, or perhaps multiple lighting engines/shaders to bring out the best from your materials and modeling. I think I understand the style you are going for, and I suspect that having the characters look like they are made of plastic/wax is not intended.
And then the most glaring issue... you need to actually model peoples' clothes. That's what makes this feel the most unfinished. There's no good justification... no earthly clothing clings to a body the way the tops on your female characters do. If that's a stylistic choice... my advice to you is abandon it. But again, I understand that might add a lot to production time, so take it or leave it.
I just want to say again, I really enjoyed this and I will be definitely be watching any future episodes!

The 3D models and animation need work.
