Regarding the centaurs, it's not considered a feature; it's a bug. As for the aesthetics, the major is right – beauty is subjective and varies from person to person, reflecting the overall style of the race. Some might find elves more beautiful, but they are essentially not warriors but rather forest dwellers obsessed with peace and harmony. Although, when it's time to fight, they know how. Orcs, on the other hand, are purely warriors; external beauty is not their priority, but this horde looks quite formidable both visually and in battle.
