Machine Learning T-Shirts by Me - Buy Some

I have been brainstorming various ways of raising money for my Machine learning self-study courses and eventual Masters Degree and I recently came up with the idea of designing machine learning-themed T-Shirts and hoodies and selling them via Merch by Amazon on-demand printing service. I must confess I'm not a great designer and have never designed a T-shirt before but I have been able to come up with some simple designs. One of them you can see at the beginning of this article: "GANimal". Not sure how people will respond to my designs but I'm willing to take a shot at this and see where it goes. Here are more of my first designs, hope you like them (I'll post some more in the future): So what do you think about them? Got any suggestions?
