One portfolio I like is Heather Shaw , especially the use of color and the big panel images. The site is responsive in that the columns reduce and images shrink, which is really all it needs as it doesn't have any sort of menu. The second is LingK . This one also has large images with minimal text, but when it turns to mobile the top adds a hamburger menu with a cool animation. The dropdown menu it opens seems to be bugged, but I like it in concept.
