A: I use Procreate to animate most of the time, though I also tween on Alight Motion and Procreate dreams sometimes! I also have a couple old stuff done in FlipAClip, but it's not common. I usually either just animate frame by frame straight ahead, or sometimes make storyboards on paper to get the idea down.
A: Procreate dreams is really useful for smooth camera movement, and I also use Capcut for effects or putting things together into a full video.
A: I really like just spacing out and brainstorming lmao. I mostly get ideas from the music that I listen to, getting lyrics and coming up with scenario to fit them (or literally imagining what the literal thing would be). I also love coming up with new OCs for music, so to be honest it's kinda where a large chunk of my characters are from.
