Make wing-it speedpaints so you can make art more rough and not worry about it as much as Illustration
> Get only complex ideas for the piece. "Maybe I can pull it off??" -> sketches way too long
> Not supposed to send WIPS. "Oh no, what if they don't like it???" -> sends sketch to client anyway
> "Damn, it looks unpolished, what if they don't like it" -> spends more hours on it to polish it more
> Overpolishes illustration because the "unpolished" speedpaint looks too polished

> Worry it wil be too rough....

I made speedpaints to stress less, and I stress over them twice as more xD This madness never ends.
One day I will find the golden middle, one day... hopefully with practise
