Hi! Yes - you can have more than photo, and more than one person (animal) in the photo. But like you say - make the bobble head the star!
OH! MY! GOSH! I groaned at this at first read! I'm like wow, what am I going to do. But I have learned to from having done MOC 6 times, that some of my favourite layouts some from challenges that seem hard at first! Once I had the idea for this layout, it all just came together. Hardest part was getting a photo of me that I liked! I love making a silly jokey MOC layout - have done a few of these joke layouts! The bobble head challenge was perfect for this! Thank you for pushing me out of my comfort zone! Here is my layout and original photo below.
Ha! The snow- is an OH YES! The challenge--- the REAL challenge is the plethora of ideas I have to choose from. This is SOOOOOOO cool!
