Since the cards are already tilted the header must be in a strict position in my opinion, so i will go with O2. Both great tho!

O2 for me, the polaroid stack feels more collectible and fits a record label better than the single frame. Since these get swapped weekly per artist, how long does one actually take you to update once the template's locked?

30-45 minutes per swap for a weekly recurring asset is a great turnaround, that's the kind of system that actually survives contact with a real deadline. Are you setting up the layering so a non-designer on their team could eventually swap frames themselves, or is this staying a task you'll own each week?

O1 for me, the mix of a light and dark polaroid feels more like an actual scrapbook someone would flip through. Have you run these by the label yet, or is this still your own gut check before options go out?
