WELCOME "Double T"!
You are in fine company here, on FM, with some great street photographer's in NYC! You have started by being proactive in the Forums...kudos...
In #1 you can see that the sun is side lighting from left and across the street. The lighting is falling off a bit on our right. The name of the botique coffee shop spelling is loosing light in the letters..Maybe lighten that side of the frame a bit? Lighten the "name" more? I love how the silhoutted coffee patron locks in the foreground as life passes her by.
#2..I LUV wall murals!! This is great! Maybe accent that with more white and more black..especially on "Mr. Monopoly"? Seperate him from the car's view..
#3..GREAT..love the b&w sheen here. The people are silhouttes! Nice...A tad brighter whites or blacker blacks?
$4..Well framed image! Would like to see the man's face more but then it may detract from the flow....(?)
The last 2
Now remember you asked for comments. These are mine and not knowing "what you had in mind" when taking these...just my $.02!
