Are these traits enough to distinguish my non-humans from humans, or would it be better to create a blood magic system? Please don't be mean; I just want to make sure I'm on the right track.

1. Halflings: Significantly faster metabolism. They need 12 hours of sleep—split into alternating 2-hour blocks of sleep and activity—and require 7–8 meals a day, depending on physical activity.

2. Elves: Partially nourished by magic, which means they need half as much sleep and food and live for over a thousand years. However, a lack of ambient magic is fatal to them, so their civilizations are built around ley lines and magic-saturated locations.

3. Dwarves: A mixture of organic cells, stone, crystal, and metal. They eat minerals and require very little oxygen. They are born mostly organic and slowly become more inorganic over time, eventually turning into statues upon death.

4. Orcs: Their social structures are based on those of chimpanzees, combined with a massive adrenaline response.

5. Goblins: Primarily herbivores—though they sometimes eat bugs, worms, etc.—and are constantly focused on survival and reproduction; they view other beings through the lens of "if it's hungry, it might eat me," or "if it only eats plants, it's a rival."

Is this enough?
