I've been working closely with the BBC Sounds team rebranding the majority of their mix artworks to give each a personality of its own to increase audience engagement. I've also worked artwork branding for a number of podcasts including The Gemma Collins podcast, First Time with Matt Everitt, Brown Girls Do It Too and Radio 1 & 1xtra's Tell It.
All mixes and podcasts are available to see and listen to here https://www.bbc.co.uk/sounds
I also help out the Sounds team create a collections of social assets for various music events including glastonbury and Big Weekend. Heres some examples from their 2019 Glastonbury radio launch.
