Does anyone have any detailed video guides for the basics of Aseprite?

I already know the tools to varying degrees

I’m having more problems when it comes to actual practicing things like shading from different angles, erasing, making some shapes

Though I’m having trouble imitating even the near exact colours or hues on the Skillshare vids

I’m asking so I can download these non-Skillshare vids for when I don’t have internet

Have you checked out MortMort’s videos on YouTube?
