Here is an image of the photo I took and the Girl band that inspired it , side by side to see how they compare.
I edited my photo by changing it to black and white and then by using PAINTSHOP PRO to select the Girls tights and used the tool colourize to enhance the colour. Here is what it looked like
The Saturdays My Band.
Spice Girls My Band.
As you can see Here i copied the idea of Using a completely Black background with just the girls faces to draw attention to their face.
