Changing Idea

I really like how my sculpture looks and I don't want to cover it (my previous idea with material). I also took the top ring away and it looks good as if my sculpture is not closed ...

Furthermore, I would still like to use mirror and that is how I thought about my new idea. I don't want to cover my sculpture so I will create something inside of it. And that something is going to be from mirrors.

Sketch of my new idea :

I want to make lots of small mirror cubes and create a spiral from them inside my sculpture. That also means I have to count again ...

First of all, I thought that I could make small Styrofoam cubes and glue mirror squares on top of it, but after I realized that if my mirror sheet is going to be 3mm thick I can count what kind of squares I need and glue them one to another :

I quickly draw this with  2D program, found 3mm thick plastic sheet and cut these squares. Then I tried to glue them and that's what I have :

I ordered 3mm acrylic mirror sheet online, I suppose to get it sometime this week. I am a bit worried, because I don't have much time left till deadline and during this waiting I loose 3-5 days.
