I'm trying to figure out what kinds of things go into a portfolio. I've asked some people I know (of whom are much older and wiser than I, o brothers) and they say that when you make one it should primarily include your strengths. I also know you need some variation of mediums. I have some works, not all of them finished but I'd like to put together a portfolio soon. Anyone have any suggestions to how I go about doing this and what I should put in it?
