Finally, some feedback! Thanks, Tiluchi! I saw some of the GPlates data, I that would have probably been easier, but I aready got a lot of progress done with the method I'm using, so I'm sticking with it. Although for a while, I've mostly been tracing from Scotese's Continental Drift, and in order to spend less time, I decided to do it more roughly, and the specific changes can be added when I do the map, like how you did. Thanks for the feedback and the inspiration!
