You can only draw your own Eoses if you get an MYO for this group : D This stands for "Make your Own."
Sometimes these can be bought, earned, or won through different means.
This is a closed species group and if you go to the Terms and Conditions, you will find the rules and guidelines.
If you purchase an MYO or a pre-made Eoses, then you can certainly draw that Eoses as much as you like <3
