Thanks Alan for the original.
This makes sense looking at the very small crop from a larger image. I have to say you did really well retaining so much detail and resolution.
You can see that metering was done for the larger scene, and you started out with blown highlights on the woman and child (Is that your hat!); RAW post processing sows that you focused you efforts on trying to reduce highlights and lift shadows, which in general makes sense. However, if the highlights are truly blown, they cant be recovered, though they can be improved, and trying to recover whats not there can negatively impact the entire image; - as the blown areas are relatively small, although important.
However, you still ended up with a decent crop. Due to the original scene, it does have some blown spots, and contrast is a bit low.
How you converted it is important, and the best way, assuming you are using LR or CS is to use the channle mixer, which covers a range of colour sliders you can experiment with. Experimenting is the key to success!
I did mods of the original, less biased to save highlights, and a mono conversion of it, just as an exercise to see what you were dealing with.
The mod of the mono crop is also uploaded. It involves a bit of cheating, in that the faces have been made lighter on their own (a layer and mask technique), and the overall image has had exposure reduced somewhat. It gives the image a bit more bite.
Its an image you really needed your Kingfisher lens for! It takes time to get the confidence to get closer with that medium lens, - and its a great lens too. So practice, get closer, and you will enjoy the variety you can get from the street.
