I use Gemini to make my pictures and the reason why it looks completely different are two reasons: I usually make sure my prompts when trying to generate the image is "2D cartoonish stick figure" instead of the regular realistic image prompt style that a lot of people do when they use chatGPT. Also the reason I use Gemini is because I feel chatGPT is too common, so I coined my own style by Prompting it to appear as 2D cartoonish, on Gemini.

I've been learning About AI usage across different models for a few months, so that's why I know a lot about how to make unique images
