Hey! Thank you for your message. I'm glad my little project has inspired you!
Unfortunately, these are two characters from my game, Dreamy Dryads, which is still in development, so I wouldn't feel comfortable with someone else using them for their own project. However, I have no objection to you creating something original that is inspired by the general idea.
That said, I'd be interested to hear what you have in mind. You can reach me on Discord if you'd like: oakhardt#5317
Have a lovely day!
