i feel like it’s still difficult to think of what to put for things like art i’ve done, but i’m gonna do my best to do give it a good effort next time
There are resources that can teach you how to describe images/create alternative text. What I wound recommend is:
Describe only what it's essential to convey the image. You don't need to describe the several shades of green in the grass or the several shades of brown in a character's hair.
Describe the important details/things as complete as you can
Give context if required. "A man sitting under a tree" isn't the same as "A man sitting under a tree as part of a protest against deforestation"
