Not bad, as someone who mains Fox is pM, I'm not super great at the game but, try to practice low jump "nair-planes" to keep pressure and make sure to use that reflector when they are uncomfortably close! If you keep practicing you will get better. What will help your fox play is if you learn how to wave-dash, It's basically a very low jump to diagonal dodge, it will slide you, it is very good for spacing when you want to dodge an attack OR in Fox/Falco's case, you slide towards them into a down+b shine. Also, grabbing is useful with Fox, like doing up throw into up air...in my own experience, those Up-Airs are hard to hit that sweet spot, so it's good that you know how to get that down most of the time. So to sum things up: Decent, but try grab comboing more, learn to low jump nair pressure and do other various shine combos since it's very good for off stage gimping. Oh and, tilt more, it's good for damaging while not getting your KO moves stale.
