Is less still more?

I’m about to do a major update of my portfolio:

Is less more? Quality over quantity? Should I put as much work and as many different projects in as possible? Or just a few case studies with a few good images demonstrating my skills with 2 or 3 images of each project with a thorough explanation?

I am still very early on in my career and every aspect seems to carry a very steep and ever changing learning curve. Am I wrong/missing the point?

I’ve been freelancing for a couple of years, my website is here and has more or less the same work on it.
