This was one of my first serious Photoshop manipulations. (I've only had PS since February.) I saw a tutorial in PS Creative Magazine on how to make fangs so I decided to give it a try.
Basically, I took this picture. Used Edit>Transform>Warp on my teeth. Used red brushes on the red background, copied and pasted my own photo onto that, made some blending curves adjustments. (5 years and 1911 days ago)
