Still picture animation

Hey Guys,I’m new to this community and I’d like to start by opening a subject no one has ever talked about in here:

Animating still pictures

I work for a local music artist who’s pretty succesful and he’s asked me to create lyric videos for his songs with just a picture of him and the actual lyrics.

I would love to hear from people who are more experienced than me in that field since I’m mainly a 3D modelling and rendering guy and was wondering what tips and tricks you would recommend to make a video of 5 minutes alive with just a picture and text in it!

I mainly use After effects and affiliated plugins.
