First and foremost of couse they are not “long” enough. Both of these bows would be 6-7ft (1.8-2m) long, more than the average men’s height. This is reflected in the unit portraits and concept arts but not in the model.
Also, as we have many diverse firearm models: muskets from different era, rifle, arquebus, pistol, etc. (in contrast to vanilla where everyone carries a wooden stick), and multiple versions of polearms for the same unit, I hope the bow model could also be revisited
It’s a really small model change but helps immersiveness with these units. Both bows were far larger than the typical ones in-game and the untis would look far more impressive with their proper welding them.
Of course there’s a big list of higher priority things, however tiny things like this would be very welcome within updates.
