Thanks for the comments everyone. Here is my ruling based on feedback, source material, and also having made CRLs for 10 years and realizing that L1 isn't meant to be "perfect" (it certainly isn't Legion wide), e.g. L1 should be consistent to other TK and non-TK costumes in the Legion.
1. Neckseal: I'm allowing ribs for L1, and not for L2
2. Armor: weathering is now L2
3. Forearm: I'll remove the # of segments, people can see if it "looks right" from the picture. The OT TK CRL doesn't mention the number of raised boxes anywhere either, not on the belt, arms, thigh ammo pack. Nowhere.
4. Back plate: I'll allow overlap on L1, but not L2+. ANH TK's are the same.
5. Boots : Yes, regular OT TK boots are fine for L1
6. Grey Lines: Yes, we should mention this as needed. Please lmk if I missed anywhere.
7. Added pauldrons. OT ones are OK for L1.
8. The stickers is relating to back in the day FX kits came with metallic stickers to simulate the metal hooks we use now. It's a legacy item I can remove.
