There is a lot going on in this illustration. Bringing it to life with sound effects adds a different dimension and perhaps clarity that you perhaps wouldn't get by just staring at it. My goal was to maintain my hand drawn colored pencil style. You will need your sound turned on when viewing this and preferably on nice rumbly speakers. I drew this in Procreate on an iPad Pro using an Apple Pencil. By the way, if you saw this on Facebook, I have since made some changes to the drawing and the sound effects.
Funny, I just noticed that the sign mobileOpolis looks like it says mobile 'police' and with the sirens I added, it might be confusing. Ha. Oh well.
I hope you enjoy.
