There are some design styles that I'd really love trying at some point.
I can't get enough of abstract artworks, especially those in isometric perspective with some nice 3D effects like the work that Jean-Michel Verbeeck created titled Abstracts. The color palette and the style is really inspiring and gave me some good ideas for a next tutorial.

Abstracts is a series of my random thoughts translated into abstract sculptures and compositions in an isometric environment.
