I recently uploaded a bunch of Forza Horizon 2 screenshots to show the liveries/paintjobs and vinyls/decals I designed in that game. Many of vinyls could double as tattoos... particularly stuff like this tribal bird or tribal elephant.
Symmetrical abstracts are so much easier to make clean and even with software. Hopefully, FH3 has improved the design toolset. I'll try to design an anchor abstract sometime. But I generally don't have a plan when I'm designing something. I just keep adding and manipulating shapes until something cool emerges (or doesn't).
