I finished sla today and can't wait to read the next novel! I must ask, what do the people of the other rhythm kingdoms look like?

A very quick summary:

Yakim: dark skin, black hair, dark eyes

Ventralli: olive skin, hazel eyes, dark hair

Paisly: dark skin, black hair, dark eyes

You’ll get to see the other Rhythm Kingdoms in more depth in books 2 and 3!
