Blue Sky visual development artist Ty Carter has a really well-written, in-depth blog post about concept art portfolios. Read parts II - V here on his blog.
Dutch concept artist and illustrator Dick Grinwis, AKA Grinwise also has an insightful, point-by-point article on the subject. Read it here.
And I linked to this a long time ago, but Pascal Campion has a really good writeup on what makes a portfolio truly stand out to him. (Pssst... it's not technique!)
Feel free to leave a comment if you guys know of any other related articles!
