I love seeing people on the street or in parks and photographing them, but I don't really succeed because they don't have to notice that they are being photographed. You did very well and I suspect why, beyond your experience in photography (I mean the lenses you use), but that too is experience and knowledge!
I managed to post a holiday walk, here's the link: Feeling The Sea (Two) - Balchik (Episode Six)
Thanks its something i rarely do I feel awkward taking photos of people perhaps because I hate my photo taken LOL
Using my longer lens did help I could take them from a good distance LOL
I will visit your post soon
