you just keep on getting better and better in you animation skills somehow and its terrifying- in a good way! also its very cool to see the more indepth concept and emotional state of your oc , since all we've been able to was a very energetic and low key kinda psychopathic "person"?, now that we see a more vulnerable side more attachments will be created to this character.
The person has a twitter, where they sometimes post art of their characters. I don't know if they talk about the characters or not, as the entire thing is in Japanese and I'm too lazy to trandlate it. The link to the twitter is in the 'About' section of their channel if you're interested in checking it out.
People use basic shapes in drawing, and then draw over their desired outfit, the shapes also must be in perspective and other various properties are to be made if this is what you’re asking; for how they draw so fast.. Try getting a drawing tablet, it should do you good if you are good at using things like a pen, and gives you more ease in drawing so you don’t have to erase as much, as a person who doesn’t have a drawing tablet.. it is possiblee.
them and sibamame seem to be good friends, I wouldn't be surprised if sibamame showed them the animation a bit earlier, allowing them to start working on this before it got released to the public
This is the first time I've observed your character very well, so may i ask something? Is that a bitemark on his neck? Also, keep up the good work. You're doing great 👍👍
