Blue vs. Eastern Yellow-bellied Racer

Hey guys. I was recently looking at the different North American Racer subspecies because, like all of us, I’m a nerd. Anyway, I have an observation that I always thought was a Blue Racer, but it has never been confirmed as one, and I have also now seen that many Eastern Yellow-bellied Racers are somewhat similar in coloration. Could someone who’s better at reptile ID help me understand the difference? I’ll also post my observation to get any thoughts you guys might have.

I commented on your observation.
