You should have posted that car here - it definitely belongs there.

Anyway, it’s not a bad first attempt, but your choice of grille makes it look like it’s frowning, especially when combined with your choice of headlights. The mirrors aren’t very period-accurate, either. Last but not least, its brown exterior color may be off-putting to some, myself included - I would have preferred black, silver, or even a deep metallic blue, green or red. At least the wheel shape is decent (given the era), and the rear is OK, although it could do with some additional detailing.
