They open a store recently in CCCats. You can get a myo for free now (in theory). You will just have to draw events and the art prompts they have set up. So if you don't mind a bit of an art grind, you can work up to it for free! (you can also do art commission for the species currency too!):O
I am unsure if you are on the website and discord but you can get a chance to get them for free during events too! I can help you set that all up if you need help!
In the discord, they have an area where people put their Skire characters in for people to draw too! So you have the chance to see more characters! :D
