AI Generative Art Based On Emotions

The following is an experiment on testing how four of the popular AI Art generative tools interpret emotions in the purest sense. Meaning just one word per prompt, no descriptive text, no mention of style, no parameters, everything at its default setting. The results shown below are the first impressions, and for the two tools that start with a variation of four, I picked the first image of the four. The four generative tools I picked for this experiment are DALL-E 2, Stable Diffusion, Midjourney, and Disco Diffusion. Note that the name of Stable Diffusion's generative tool is now called DreamStudio.
