Is it worth it for me?

I’m a high school student looking to make an Etsy shop for the purpose of college applications. I’m not looking for any amount of significant income- a couple hundred dollars in a 2-3 year period would be excellent for me.

My proposed business is one selling paintings for probably 25-40$. I would likely never have more than 4-8 listings at a time.

My question is how reasonable and achievable is this, and how much effort would I need to put into this?

Also, it would be great if you could tell me what type of landscape painting (I paint landscapes) you would personally buy. Please include main color themes, and important features.

Any additional advice is welcome!
