Sure, most portfolios only show the good stuff at the end. However, for pure authenticity, I sometimes like to include the gritty beginnings of a project. You can scroll on past, nobody is stopping you. Otherwise, enjoy my sharing of my process.
I could have used a digital art pad, but I grew up illustrating on paper, so my process always starts there. My process did evolve as I went, to speed things up. I found ways of taking quick sketch ideas and moving them to a digital artpad quickly.
Some parts of the storyboard were illustrated poorly to get the idea down quickly. Some that were a little more solid in my mind I was able to add more detail to. It would all be refined later before animating anyway, but this was enough to do an animatic and get proof of product down.
