Shape doesn't look right for Crested Goshawk--as it only has five "fingers" rather than the expected six for Crested. I wouldn't want to say whether it is Besra or Japanese Sparrowhawk from these photos. I believe this bird is an adult and the presence of a dark mesial stripe would make it a Besra. Unfortunately it is too dark to see that feature in this photo. I would suggest lightening the photo to see whether a mesial stripe was present.
