If you have logs of yourself (or can get them - you'll have to get a friend to upload since you're PS4), you could try the xivanalysis tool - that should point out any glaring mistakes in your rotation. You could also find your way to The Balance discord and ask in the MNK channel if someone could look over your logs and tell you where you can improve. The general channels there are full of memes, but the job-specific theorycraft is solid.
