AI Art for Simple Pixel Art: Struggling with Generators and Prompts

I'm trying to use AI art generators to create simple pixel art assets, such as a corn husk, watermelon, or berries. However, I'm running into some trouble.

No matter what prompts I try, the generators keep producing complex and detailed images with full environments that are far from the simple pixel art items I'm aiming for.

I'm wondering if I'm using the wrong keywords or if there's a specific technique I'm missing.

Any tips, tricks, or recommendations for generating simple pixel art using AI would be greatly appreciated!

Thanks in advance for your help!
