Point of Purchase or Retail Portfolios

Hello! Does anyone know of any examples of great POP/Retail portfolios? And/or any hiring managers with any input of what they are looking for?

One thing I’m really confused about is sketching/process pages. While we do research, at my company we move so quickly that we usually jump right into 3D modeling and no sketching is involved. Should I add some in retroactively?

Thanks in advanced!
