Deviant Art user minidelirium has created some of the most intricate papercraft art I've ever seen. She has created crafts of all sizes from a mini Kupo to a huge Zelda model. You should definitely check out her profile and look at the progress photos and more detailed shots of the characters.
It's been a while since I posted a something geeky. Here's a wonderful set of digital art portraits from Teenage Mutant Ninja Turtles to make up for it. Dave Rapoza brought these characters to life using intricate textures and a superb attention to detail. He also has some portraits from Heman and Thundercats, so check out his portfolio!
Deviant Art user LadyAdler combined her obsessions of Alphonse Mucha, 50's style pin ups and Disney princesses to create this beautiful set of Art Nouveau illustrations. I love the flourishes and background elements in her work. They add a lot of depth and meaning to each piece.
If you like these, don't forget to check out the rest of her portfolio. It is chock full of more great stuff including original works.
