But I didn't use neural networks 😎
Regarding the tenth one, I've seen that style before. If you look closely, the brushstrokes aren't very human-like (and there's an unclear signature in the lower right corner; the neural network couldn't identify it). Also, a few strands of hair on the right side of the head are floating in the air, not connected to the head itself.
My ninth one is identifiable by the textures of the clothing, eggs, and noodles (and I've seen the whole series of these artworks; it's more noticeable in some of them).
