Hey! That's great to hear! There's not a "test" per se, but it helps if there's a way to get an idea of your skill, experience, and style. The best way to do that is if you have a portfolio or examples of your prior work that we can take a look at. If you'd like, feel free to get in touch with me on Discord (Roan Arts#5750) and we can discuss more!
Great, I sent a discord invitation.
I don't really have a portfolio but check out my newgrounds account https://theastra.newgrounds.com
