A portfolio is an opportunity for you to present your work, but it is important to consider what the portfolio is for. Are you taking it to a job interview, or are you looking to get your work exhibited at a gallery? Maybe you just want to bring your work together to present it?
Whatever the reason, it is vital that you create your portfolio with this in mind. A job interview might require you to display a variety of skills and techniques, whereas a collection for an exhibition would require a single unifying theme and will need to be presented with the gallery setting in mind.
