I made up this stupid story about an octopus falling in love with a plastic bag with a weird ass cliche'd message to "pls stop poluting the ocean :(" and some other stuff.

I love this message you tried to convey. And you have conveyed it into a story with cute little ortopus. This is a good story for kids and start to educate them.
Thank you for sharing with us on how to start your art story step by step. And the final piece is beautiful after you can colored it. Hope to see more of your work @maya525
