If thats your first time wearing the armour its not too bad, just some adjustments and fine fitting needed... Here is what i noticed;
I dont think the boots will clear due to the extra stitching of the panels, check with your GML.
The shoulder straps dont seem to be attached? Glue the front ans free to float at the rear.
The shoulder bells need to come up closer to the straps, and lower the biceps.
I would remove most of the return edge off the chest plate, there seems to be far too much there.
Spin the forearms around so they are in line with the rest of the arm pieces.
Trim the O2 tank / thermal detonator it want to be closer to 7-5 inches in total including the end caps.
Some general tweaking with the strapping cant go a miss, you will find this out when you get out and troop
