Evaluation :
I am satisfied with the overall appearance of the final image and the techniques used to achieve it. However, if I was to be extremely critical I would say that the skin retouching has made the subjects skin slightly grey. Although, the blemish and wrinkles tool worked extremely well for removing some of the skin imperfections. One disadvantage of the technique is that the background colour is also altered but it is something that can easily be adjusted. Therefore, the techniques are something that I would implement again in the future when editing images in Photoshop.
