Though I'm not a designer, I've designed some wallpapers based on design principles.

i like their simplistic style, good start!
Altought it might be just my opinion, but some of them would benefit more from some illustrations less tight coupled (you can take this as a suggestion or design principle as well).

For example, the Open Close principle seem to suffocated, without a big enough resolution, the spaces between classes might get hard to distinguish.

Anyway, good job once again and thanks for sharing, the Community loves ya! 😉

@KennyTheBard It was hard to think. But I thought to design programming related wallpapers where they can't only decorate the monitor but can teach us.

Hence I created an opensource project so that even other's can submit their ideas.
