What medium should I use to express myself? I kinda already chose it but I don't know if it's the right thing, let alone if I'm ready to start publishing

Hi, a couple of months ago I decided that the best way to express myself was through stories and drawing comics, and not just writing. I post this on this subreddit because I think the writing process is the most important thing on any comic or any other medium that deals with storytelling.

I've been posting on facebook for years my opinions about politics, society and stuff; and I was pretty satisfied with that. However, after all this time I realized that I disregarded my artistic sensibility with visual arts and music, so that's why I thought that expressing myself through some stories would be an even better experience for me and my potential audience.

So, I created a world, some settings, and characters.

Talking about the comic medium, I'm not very sure what specific format to choose, and how much can I write for the plot of the comics. I made an instagram account, a site where you can post a maximum of 10 pictures each post, so I told myself "well, you can start by writing microrrelatos (short stories) to get used to that limited format". Do you think I'm heading towards the right direction?

As a side note, I don't know if my drawing skills are good enough. Perhaps I'm ready to post on ig, I can show you my account with a drawing example if this is allowed (I'm new to reddit, this is my first post), and tell me if I'm ready to start posting. Thank you in advance.
