Hey Darcy,
I am so glad you posted these here! As great as they looked on FB, they sure look even nicer here.
You have me wanting to head to the airport now with my camera!
The motion in all of these are great. Were you using a tripod? Because you got some great motion while keeping the shot itself sharp.
In #1, I like all of the stationary people and just the cars moving.
In #2, I think it's great all of the people moving and bustling but one... and he is staring right at you! What a great contrast.
In #3 again a lot of bustling movement but then the one limo driver is pretty sharp and holding that sign.
The choice of B&W is great, and works well with these city/street type scenes.
