I love the colors and I disagree with the comments. it's easy to get lost in the cities like this one and it's extremely easy to get lost in Hong Kong. I love the tiny people - it's very close to life. it is indeed not very easy to see people and especially individuals in this atmosphere. I don't understand why everyone wnats people to be closer to the viewer:)
Your horizon is not level -- this needs to be rotated clockwise. I also feel like the people in this photograph are almost a footnote or afterthought. With so many loud colors competing for attention, it's hard to know where to look -- or what the story is.
i must admit i am not a fan of colour street work. sometimes it works and other it falls flat in its face. This just about works as the colours are vibrant and punchy. the thing that spoils it for me is that the couple is a little too far back in the shot. and there is a little lean to the left.
