Your combination of shirt, tie, pocket square is good to go.
Adjustments: Your shirt collar appears to loose - you need a smaller neck size. Your tie knot is a bit large and could use a dimple. Pocket square could be more aligned with the angle of the top of the pocket (or use a looser fold which can be more loosely aligned.) To me, the very simple TV fold you've used is fine but I prefer it when this sort of fold aligns pretty much exacly with the top of the pocket.
I definitely agree with the rest - but I don't think the PS has to be aligned. Personal preference, I suppose, but not aligning it is an exceptionally easy opportunity for sprezz.
