No idea, but if you want any tips the way i did it is by meshing a bunch of images together and using texture brushes and filters, you dont exactly need firealpaca for this, its just what i used since i was comfortable with it
also, do you have discord? (please respond as soon as you can i wanna show you something that you inspired me to make) (i like to think i used some of your advice) also you don't have to if you don't want to just a mere suggestion :]
