This is a fairly good guide for Fox. You shouldn't sleep on the F-tilt, though. There was several opportunities for you to punish that guy with an F-tilt in that video you posted. It's good for shield pokes (if properly spaced) and can be used as a quick "get-out-of-my-face" option. It is also a safe attempt to punish rolls (if you don't want to hard read them).
Likewise the down-smash is good for horizontal knockback, especially on characters with sub-par recovery (Little Mac, Dr. Mario, etc.) The forward-smash can be used to punish rolls on reaction (the up-smash would be better if you read the roll).
Throws are situational and can be used for combo potential OR stage control. Up-throws could be good under platforms, and back-throws could be good at the edge.
Perfect Pivot tilts are a good part of Fox's game (Perfect Pivot SS Down-tilt into Up-air), though pivot down-smash could be just as good imo.
Also, are you aware that you can cancel ledge jump into any special move at the correct timing? You can cancel it into a standing illusion (Not sure why you'd want to, but...) or an invisible shine (if you're frame perfect). This can be good against people who spam projectiles off stage, and is a great deal safer than dropping from the ledge, burning your double jump, and then shining. If you perform it correctly, you will also be able to instantly roll or jump out of the shine (if you reflected something), as it is considered a standing shine. Not necessary to be good with Fox, but extra options can never be wrong.
Your guide was great at explaining the properties of moves, and it did have some good combos. Your section on mind games was excellent, and something I'd recommend to any Fox player. The section on throws was also necessary. Grabs are a pretty big part of Fox's game because his offense pressures people into trying to shield-grab. Though, I would strongly suggest that you upload a different gameplay video. While it was successful in showing the value of mind games, the sub-par play was somewhat detrimental to what you were trying to prove (Against average or below-average players, mind games are usually a waste of time. Random players are random, regardless of mind games.)
Please, keep up the good work!
