Portfolio project advice

So me and two friends were making a point and click style game, inspired by Myst and other games. I’m in charge of the coding, one friend has done the concept art / story and another was going to do the 3D modelling, but has bailed from the project for unrelated reasons.

90% of the coding and functionality for the demo is done, but it’s all 3D primitives.

I want to use this project as a portfolio piece to show what I’m capable of from a programming stance, but if all the assets are barebones, I’m afraid it won’t be taken seriously. Should I find someone else to do the 3D modelling, do some basic 3D modelling myself, or is it something not worth worrying about?

for what it’s worth, here’s 20 seconds of functionality and the current vibe the of the project.
