Broadcast Messaging

Hello People, I hope everyone is doing great.
Here is another challenge I worked on this time it is a Messaging Broadcast System. The web app helps people to send bulk messages.
It's a 4 step process, and I have only created a design for one step where users can select or bring a group of people onto the system to whom they want to send messages.

Created designs in black and white themes both.

Cheers!
