Feedback on Data Visualization Portfolio

Hi everyone, my name is Tadi, and I recently put together my portolio of data visualization projects. I was recently retrenched from my job as a data analyst here in South Africa, so this portfolio is meant to help me launch some freelancing activities on the side while I look for something more stable.
Would love to get your guys opinion on how I present my projects and any pointers on how I can get clients through freelancing or other gigs from my skills. Thanks!
