After taking a moment to inspect the turret placements, I think I can safely say that their coverage is really well thought out. At a glance, it appears that only one turret cannot fire forwards, with only two being incapable of direct rear fire. Directly from the sides, I see only three turrets left out, with similar stories being true of straight up or down fire.
I keep looking at it from different angles to see if there's anything that seems to be a flaw or out of place, but I can't find anything of the sort. I love how the bottom "rib-like" extension beneath the pods has a jagged, zig-zaggy pattern when viewed from the sides. 10/10 from me!
