Nicely done. One thing I think is missing is using the power of FCP's roles and subroles not only for organization, but also for sub-mixes and busses. The whole timeline is essentially a large flat thing without a lot of differentiation. There's no discussion about connected audio clips, sound effects, fades/dips/ducks or dynamics processing. If you approach it right, FCP can pretty much do anything (apart from frequency shaping), but it helps to spend some time with roles to get the most out of it.
