Nice, is it a kid kit?
More seriously though,looking at the picture i think you should lengthen a bit the three straps between the abdominal plate and the chest plate. Right now, because they're too short, they're pulling the abdominal plate down creating a shift at the side junctions and a gap at the crotch.
Unfortunately with your height you will have much difficulties keeping the abdominal buttons fully uncovered.
Once again, using Luke's reference, it doesn't look silly if the ab buttons are half covered
