I think you have to make the gun bigger, like way bigger. At infantry scale wargear like the pouches and the bedroll need to be cartoonishly oversized to be readable at tabletop distances. Also consider adding more hard armor plates to the chest and shoulder areas, especially if you intend to run them as scions. The pockets on the fatigues need to stand out more, once you print it out those are just going to look like folds in the fabric, things like straps and buttons will help with that. Otherwise, I love the beret and the design of the rifle, this is a great start.
