Rough Modeling

No.502546 ViewReplyOriginalReport
Arca's new album cover by Jesse Kanda.

In many interviews he declared to use Cinema 4D for his artworks.

I'm pretty new to this program and all the tutorials about modeling I found are about interior design or abstract animation.
What about something to modeling materials in this rough way?
I tried to get close to this result using tool as Magnet and Iron but I see that is not the right way to do this.

Any tips?
