I usually love ambient lighting but in this case I think direct sunshine would have been better. Some of the clothing (the non-actors) is not consistent with the period it suggests (car). Right hand figure looks contemporary, girl in polkadot dress looks 50s, and men didn't wear denim jeans in the 20s? unless they laborers, let alone skinny-jeans, >1960s.
It's a very nicely constructed scene and I really don't want to diss it but these things kind of spoil it for me.
