Looking good, your images are a little small, very hard to magnify to see details, larger size/resolution would be preferred.
Watch the heights of your thighs, they don't appear to be the same levels
Belt/abdomen on an angle.
Forearm to wrist/handguards different gaps.
Angled back plate, you may need tighter strapping.
Thighs touching posterior plate, try adjusting thighs. Your shins could come down they are high on the boots.
Detonator could be rotated slightly to see more of the O detail
There is some velcro showing between the forearm and handplage
Can't make out if you have a "Han" snap
There are some areas on your blaster which appear to have print lines. For L2 and above, see what your GML requires.
3-D printed blasters can not contain visible print lines, and must be sanded smooth for a more realistic appearance.
I don't see anything glaring that should hold you up for basic approval.
Good luck, hope we see you approved soon
