This is a great question and I have been asking this myself. I have around 10 years also and in the midst of redoing my portfolio which has not been touched in a few years which means its way out of date. At this point, my approach was to do maybe 6-8 full process projects and then a bunch of beauty shots. I would sub projects out as needed to best fit what the company is looking for in the way of skills. Beauty shots would be used to show other projects that strengthen the process projects and show other skills. But I have gotten through 1 whole project so far so not too far along in this process. it will be great to see other peoples response. Thanks for posting this question.
