Welcome to Steemit!
It's always awesome to have more talented artists in here 😃
You can use Dtube for posting videos and Steepshop for pictures with a very similar to instagram interface, both of them run as applications based on the Steemit platform, so they're all linked :)
Thanks so much! Glad to be here :D
I will definitely check those apps out! Really want to reach as many people as possible
