Street photography is one of those areas of the art that tends to divide opinion, if you approach and engage your subject is it still street photography or should they be entirely candid shots with no interaction between photographer and subject.
Personally I think both approaches can work, it really depends on the type of shoot you want to do. This second batch of street style photographs were candid shots taken in the early afternoon, there was no interaction between me and the people (or pigeons) I shot.
