Hi reaganza23, thanks for your support. I don't have any tutorial for this work, in fact the process is really simple : you need to make a basic & clear shape of the picture with a single or several threshold filters. Then the shape is re-build on top of that with words. That's all.
The key is to be really precise to get that clean effect, it requires time and many adjustments. Honestly this picture is kind of a prototype, I consider the next type portraits I made better than this one.
