Rather than in the previous urban portrait which I made high key so reducing the color in post processing, with this one I have saturated the color to emphasize the color in the brickwork. The place is an old railway arch, water has run down the walls to create some amazing colors as a backdrop. A good tip is when you look at color, see what you can do with it rather than always just as it appears. The clothes chosen were to match in with the backdrop. Saturating the colors in Lightroom also added the emphasis to the girls red hair.
When posing someone in this type of scene, look for something that adds interest to the scene rather than just a straight pose. Urban portraits should be a little edgy not like classical portraits. The great thing about an area like this is that the light is lovely open shade which in nice and soft and allows you to vary things as you require.
To turn your photography from recording an image to art is making a scene your own. Look at the scene and see how you would like it look to look then make it happen. You will find plenty of tutorials on You Tube about working with your RAW files, watch and learn from them.
