Hey, Eld here, Community Manager for AHITR. I'm sorry you feel as if your first experience in the Discord was "Hostile".
The AHITR Discord server welcomes everyone and anyone to join, hang, discuss everything related to AHITR and other topics (Like music, video games, sharing your pet photos and so on).
It appears you joined and offered your AI art skills to Zanith for AHITR, which is very generous of you. However, Zanith, myself and most of the team operate on different time-zones so we weren't around to answer your questions directly, sadly.
I see that several members of the community politely replied to you after you weren't satisfied with the wait time of your last message, and further pointed you towards the appropriate channels to post your art. I can also see you left on your own accord after being further dissatisfied.
You're more than welcome to return to the Discord if you'd like, but communication and respect is a two way street.
Much appreciated for your time o/
-Eld
