Which size photo in Thanks you card?

[ha98ed14]

DD has her last speech appointment this afternoon. I picked up a Thank you card and a $25 gc for B&N. I plan to put a pic of DD in the card, but I can't decide what size. I have a 4x6 full body shot or a 2x3 head shot. She is smiling angelically in the 2x3 and laughing in the 4x6. The SLP often tells me that DD is her favorite client because she has such personality. WDYThink?

[truly scrumptious]

Laughing - it seems so much more natural - and probably in line with the SLP's comments about her personality. It also makes the card seem less like a standard go-to card and more personal to have a candid-looking pic.
The full-body/laughing one would be my choice.
