Also don’t ever forget, it’s totally ok to have a go at it again if you feel you need to start over. I was once trying to model a helicopter, I kept iterating over and over because each time I felt I could do a bit better. And of course, by the fifth time it was a day and night difference by comparison to the first attempt. So go all the way to finishing your character and if you think like you know what, I’m going to start from scratch, don’t hesitate to do so.
