Architectural model concept

I’m currently making this twisted tower (1.65m high) in concrete material, from 3D-Printed molds, since august 2016 (construction would be finished in few months). 3D-designed on SolidWorks 2016.

Feel free to share in comments your opinion about the design or any suggestions you may have, I’m opened for any ideas !

Thanks for checking-out my work ;)
