Hi there, with Imgur try to use the "direct link" so your images will show, or right click, copy, then paste into your post (FYI I've just edited them for you) info on using Imgur here
A clean build I don't think you will have any issues for base approval, albeit that is entirely up to your GML (Garrison Membership Liaison)
For higher levels I would drop your brow trim down a touch, if you look at both sides in front of the traps you have a slight kink in the trim.
Not sure from your image if you painted the bumps on the ears or the in between, I see 3 or 4 bump ears may be used for base clearance (see how they appear evenly spaced), they could be tidied up a touch mainly the bottoms.
Basic
The “ear” bars have three or four bumps and are painted grey, with a black outline. Painting the bumps with rank stripes (highlighted) in black is optional.
For L2
Ear bars shall have four bumps only, not three.
For L3
Ear bars shall have only two to three bumps painted in black (rank stripes).
You can see a lot of opening behind your shins, many use a heat bath to soften the plastic and allow to bend
You mentioned the boots, the ones you have used the shins are siting up a tad, especially your right.
Can just see a gap under your shoulder straps, not sure if you can drop the chest and backplate so the gap can be reduced.
Your gloves appear to be rubber (shinny) and appear you have stitching as well as elastic loop.
OPTIONAL Level two certification (if applicable):
If rubber gloves are worn the hand plates will be affixed via an elastic strap over the palm. No stitching/holes are permitted.
If silk or satin gloves are worn, the hand plates have the correct visible stitching with a 5 point/star pattern, equally spread out with 2 on each side and 1 in the middle front, double stitched with 2 holes at each point and sewn to the glove at each one using black thread.
You could drop the belt at the back a little
Also
The top of the ABS belt shall sit at or just above the bottom of the central and vertical ab button panels. A slight overlap is suggested, but not required.
Your left forearm looks a little on the large side, you can see a gap in the rear photo
Also centralize the detonator and align belt closure. Note the gap on the left forearm compared to right. Your helmet could come down a touch, sitting up on the back.
So just a few tweaks and you should also be ok for higher levels.
Good luck and hope to see you approved very soon
