I genuinely seem to be anatomy-blind, I don’t notice these sorts of things at all on human figures.
Oddly, i DO notice when it’s Horses. Maybe I just think ‘toy soldier’ when looking at a human, and only go ‘Horse’ when I see a horse. Or in the case of some manufacturers, ‘Not Horse’. There is one company whose figures I really like, but if you showed me a horse that looked Like their horses, I would tell the owner their dog needs to go to the vet.
