I’d say go through the sculpting courses that interest you most. Yes there will be times when you need to watch another course to find that tidbit of info to move forward, but don’t waste time learning something you’re not going to be using anytime soon. Just In Time Learning is how I like to approach things and it ensures you’re learning what you need at the moment instead of “stocking up” knowledge that you may or may not use. It’s also a lot easier and more enjoyable to learn this way.
We have quite a few sculpting courses so you should have plenty to look through. During the process of sculpting you may find that you want to explore other topics. Don’t feel like you need to follow a rigid schedule or list of courses to move forward. The flows are meant to be guides for those who have no idea what they want to pursue yet, but if you do then do that.
