While the general concepts are there, from my perspective, these are more draft level of detail for guns, I feel your friend could work on figuring out form a bit more, as i see a few placed where it seems theyβre unsure of how to execute, for example, some of the triggers look like fishing hooks, or the mag for the AK looking like a trigger, they use so minimal polys, i feel like improvement would be had if they tried to go even more detailed with these, as theyβre so simple they look morphed a bit.
