When designing technical documentation or video would hand-drawn sketchy elements seem out of place?
For example I have a Printed Circuit Board with switches and connections on it. The title is a very geometric overlay on the bottom with the name of the component on it in a Sans Serif font. To then highlight the component on the PCB I could use another perfectly geometric, vector shape. Or I can draw something by hand to give it a bit more character.
I prefer using the hand drawn feel. I think it adds more character and helps draw attention to it by being a contrasting style. But is it better to stay consistent and keep the mark mechanical to match the title and board?
