I regularly come to this page to learn from other people mistakes, so I’m not the right person to give advice. However I couldn’t resist myself to comment. The NYC sets made me nostalgic. You captured the real life one can see in such a great city, only if we open our eyes instead of rush to catch up the daily routine. Life, humanity, art, and details of the urban environment are conjugated in this pictures and gave me a wide range of emotional memories, as I found a story in every single picture (BTW, I’ve never been physically there). In the Heights I love the first one most. I know the exposure time was 5 sec. Did you make some postprocess in the sky?
