Nice to see, that you haven´t given up on this one 😊
I will try to give you some comments but it is really hard to see the details on your pictures, it would help if you take them in a better light.
If you could take pictures of each part in good lighting also, that would help a lot.
I have a couple of things that I noticed right away, and that you will need to correct :
If possible could you lower your chest plate a bit ? the chest and back armor do not need to touch under the fabric bridge - you can extend it with velcro and then make the bridge fabric a bit longer. This will also make it more comfortable for you.
Your shoulder bells sits to high, they need to sit on the edge of your shoulder, the correct position will also help so your flakvest sleeves do not look to long.
Your pouches on the cummerbund needs to change sides - easy fix - but they also needs to be higher up so the top of the pouches sits under the edge of your chest armor and moved more towards the ribs in front without covering them. We shouldn´t be able to see the flap that they are hanging from.
The closure on the cummerbund in the bask should sit in the middle, that will need to be changed.
Your dropboxes needs to be lowered a bit too, the straps are to tight and its hard to see if your clips on the straps are put on the right way.
The clips on your gloves will need to be cut of.
The bolts on the helmet will need to be painted black.
With better pics, I can give you more feedback on the rest, that I can´t see in full.

Keep going, you´re almost there 😉
