I should have thought of more structure before I did this. Don't you also hate when you find out you've been working on the wrong layer all along? And in the end I decided to stay on that layer. So I couldn't do any/much undos here.... Ahhh.
Aside from all that. I did discover a faster way to get things done. So I'll be trying more of this technique later. Maybe it's 'cause I started on paper... Hmm
