Free Offline twitch picture

Hi all =)

I recently started streaming so I'm looking for an offline picture that would work for me

Can say offline or follow to know when i'll be back, something like that.

Colors? I like purple/pink/black/white or anything you guys would think would work best

Needs to be 16:9 so it will fit the twitch screen

I recently saw one with stars in the background fading in and out, but I'm flexible. I'm looking for something pretty and eye catching.

Thanks guys <333
