Overall a great introductory text for freeform solo. I feel like you could've talked a little more about the benefits of freeform combat, such as being able to control the pacing of fights, using only one die roll to resolve fights against minions if you want, and how much you can adjust the consequences of failure to suit the story's tone. However, these are more advanced points that aren't necessary to cover, so I still feel like the guide isn't missing too much.
Another thing I think could be useful is a list of good random tables you've enjoyed (and potentially other resources for freeform solo in general).
I think you've done a great job covering the basics, but there is still room for more improvement. Rating this as 4/5
