It's a decent attempt but there are a few things you still need to work on.
-The ab plate should sit over the cod, not behind it
-The vinyl shroud should not stick to the face plate so much, it should be a seemless run. If you can, peel the vinyl off the plate until it's just being held on at the edges.
-The band you added around the helmet could use a little more work to smooth it out.
-The face plate shouldn't be a different color than the rest of the helmet. I'd recommend a full tear down and repaint. This would let you work on the brow ridge and reposition the vinyl as well.
-The backpack should sit higher up with the top level with your shoulders
-The backpack colors are off. Where you used a silver paint it should be a middle grey the same as the one used on the TK helmets. The same goes for the thermal detonator body.
-The backpack is put together incorrectly, the side plates should be inside the front and back, not overtop of them. I don't know how you attached them but if possible switch it around.
There are other things that are a little nitpicky but still technically inaccurate. For completeness they include:
-The red circles in the top part of the back pack side plates aren't supposed to be symetrical. The one on the left side (when facing the pack) should be about twice as large.
-The grey box shape that's painted over the top left of the backpack should stop at the top, not run all the way over and down the back.
-The boot straps should be weathered to match the boots
-There shouldn't be trim around the bottom and side edges of the helmet.
Things like the white instead of tan duster, elastic around the upper forearms, modified laces and the holster are acceptable options at this time.
You're 85% there, a little bit of reworking on some parts and you should be good to go.
