The_Traveler,
no way! It's not the camera that makes your photos great, also not a PS job, crop, Nikon Sensor or similar. If you had used a cheap P&S for these, the photos would be great again.
The point is in the time and efford you invested to make these photos. You went to a place, where possibly not all of us would go (because of the political situation, criminal, whatever). You looked for subjects and went to districts, streets -probably very poor districts-, what for most of us would be a nightmare. You dare to take these photos, even more: you looked for good composition, etc. Maybe you talked to these children, give them a chocholate, to pose you; maybe you didn't; maybe you were the whole time in danger: who knows, not everybody likes when a stranger take photos of his children. You could have even be lynched.
Also, as said here before, you had a good sense for the photos.
My uncle (+80 years), is photographing for 55 years. When I talked with him about his photos (award winning ones), he wondered why do I always ask what lens, what filter, etc did he used in some of the cases. Stupid approach -for example- for a photo about an old man sitting and smoking in one of Kairo's side-street... Or a city market in the capital of Tadzikistan... Or for children in white clothes playing in abandoned harbour in Maroko... My uncle took the time, money and travelled for example once to Tadzikistan 40 years ago, alone, just to make some nice photos. He showed me one really nice. He said, the rest is not so good and actually he didn't found the motivs, he was looking for...
I go out with my son, after I get home from the opffice and take a photo about of him playing in the playground here in Vienna, but it can not have (me at least) that WOW effect like these of yours... And I have also not bad equipment...
