The next band member we will be drawing from the band '5 Seconds of Summer' is one of the cooler looking ones. Here is "how to draw Calum Hood", step by step. Now Calum Hood was born on January 25, 1996 and that makes him eighteen years old. He is of Asian ancestry and is the bassist of 5 Seconds of Summer. I know he has a huge fan bass or following because I did some research on this adorable bassist. Anyways, have fun drawing Calum Hood, I will be back with the rest of the band so stay tuned in.
