PROGRESS - I watched the video that Ms. Fisher posted and followed every step in there along while I perform on my own computer.
ISSUES - When I was trying to change back to the normal pen function to outline the next area while moving from layer to layer, the already filled colors will also be changed into the new pen color. I found the solution which is to lock the previous layer, but I'm not sure if there are other ways to do it easier.
GOALS - I'll try to go to the engineering tutorial to ask Ms. Fisher my questions and hopefully be faster at switching between different functions.
You did a great job on tracing the objects out, and all the objects are well connected. Maybe you can delete the black lines between two objects to make it seem more delicate,
