Not terribly big, but still certainly intimidating.
Do you plan on making any chrysalids or mutons in the future? Those two were some of the most scary gribblies I think. Chrysalids mangling operatives after emerging from beyond vision range and then disappearing from sight during night-time terror missions... Eeeesh
! And mutons being as tough as they are is all the more worse when you don't notice them on-screen because they're the same damn colour as the ground. I've propped an agent or two a few cells away with rather obvious outcomes.
I keep thinking of attempting an X-COM/UFO game with minis, but it's just more easier to play one of Julian Gollup's fine alien-related tactical games on my computer. Though making the figures just for making them would be fun.
