See the 2pics - one is from 5 days ago, the other is today. I haven't watered in 4 days. I'd this what it would look like if it is thirsty? Thanks!
the leaves will be drooped and "soft"er if it is under watering. Over watering they will droop but be more rigid. https://www.youtube.com/watch?v=pL1qM_IlekE
