create a series of digital photo collages/montages that share a common theme, stylistically and conceptually

I want to use the following attachment to create a series of digital photo collages/montages that share a common theme, stylistically and conceptually. I need to have photoshop effects and anything else to make this stand out. Use Photoshop’s help to create a series consisting of 3-4 separated pieces of well thought out and well constructed artworks. These pieces should have a coherent and unified theme. All pieces in a series normally have the same dimensions; however, feel free to explore other possibilities. Be creative about your dimensions. Pay particular attention to the composition of each piece and the unity of the entire series. Your might consider nicely mounting your finished 300 ppi pieces for portfolio purposes. Imageries depicted the series should challenge our conventional way of thinking, doing and living in a unique and unexpected manner.
