I actually have my portfolio arranged to showcase specific skills. The first pages are for hand illustration, then categories for photoshop, landscape design, planning, 3d modeling, etc. I lead with my best work as others have mentioned. I figure since I have little experience and hiring managers will be looking at a hundred other portfolios I should cut to the chase and present the skills they’re looking for. I’m not positive this is the best way to present my work, but I think it will make my portfolio stand out overall. I also don’t bother with paragraphs explaining my projects in detail as I can do that on my resume or, ideally, in an interview.
