This is really amazing!
Welcome to Steemit! You're in for quite the ride. ;)

As a pointer for the start, you could do an #introduceyourself post, where you, well.. basically introduce yourself to the community. Say a bit about who you are and what you do. :) It is generally recommended to post some sort of "proof of existence" usually in the form of a photo of yourself holing a paper with the date and your steemit handle on it, so people know you're real! :D

You can omit your face of course if you'd rather not show it haha. get creative ;P

People here also love to read a bit about the process you go through making your art, and if possible, with some work in progress pictures too. This also serves as proof that you are, in fact, the author of your content and aren't plagiarising. :)
Unfortunately there are a few people here who do that :( hence it's always good for artists to show a bit of their process from time to time.
Besides, people like to read that stuff and slightly longer posts also tend to do a bit better here anyway. ;)

I hope you have a lovely experience on steemit, and we would love to have you in our art community, @steemartist here on steemit and on our Discord channel if you feel like it.
We're always happy to welcome awesome new artists and we help each other out on our steemit journeys.

toodelooes!
