The Many Moods of Sam

As many of you know Sam is my 4 year old son; my one and only. He is who I started making toys for until there were just too many gnomes in the house (it's still a contention in our house if there can EVER be too many gnomes.) Then I started making toys for the rest of the world by selling them in my etsy store Simply Playing. One of the items I carry is knitted play crowns, and I've tried using Sam as a model for these crowns. This is not an uncommon practice, using your our child as a model, but I feel I don't quite get the results others do. Simply put, Sam does not want to be a model. I have to bribe him with a little screen time of Thomas the Tank Engine (not very Waldorf of me I know.) So, our photo shoots are a very quick affair with lots of direction and not a lot of listening. But, I feel it's important to give the buyer an idea of how the crown looks on a child, not just laying flat on my counter. What I'm wondering is should I use his photo for my main picture (this is the only picture that is shown to the viewer on etsy until they select that item and see the other detail photos) or should I use the flat crown photo? Here are a few pictures showing the many moods of Sam to give you an idea of what I'm working with:

Are they endearing to others and not just his Mama, or do they just look unprofessional? Her's the flat only crown photo for comparison:

Which photo would draw more people in to look further? I've tried posting a mix of the two types of photos, but I can't tell the difference. Let me know what you think.
