I used reference for the radio, which took a long time to get looking “right” because I didn’t want to cheat with real straight lines. I now understand why the Draw a Box tutorials have you start by drawing pages of lines. Drawing lines is hard!
I also had trouble with the gum gum person’s legs, of all things. He’s sitting on a beanbag chair, for which I used no reference. The shading makes it look like it might be a lump of coal instead. I can live with that.
And yes, Prompt #3 is currently missing. I hope to get it done tomorrow(ish).
