I aslo played about and created some digital photo collages which I think work very well. The one that worked out best for me is the one in which I selected the parts of my face with makeup on and applied them over a photo of me without my makeup on. Also the image of my side profile in layers, I create these images using a basic crop and paste tool on a simple pc programme.
The other images I just create while playing around with different software and setting to see which one I liked the best. I think they work well and give the images a more of a cartoon effect to them, I think the one I think is most affective is the build-up piece using square and a copying effect and the image I used is the one of me facing myself as a reflection with and without makeup on. I used an overlap tool to create this effect on the image. The simple images work well also the ones that I have just changed the order of the photo so my chin is at the top and my eyes at the bottom of the picture.
