Stunning silhouettes under European cities reveal the size and splendor of the continent’s urban foundations. Photographer and content-manager Anna Arinova, 28, from Moscow, captured the awe-inspiring labyrinths in Russia and Germany. Here: Regenwurmlager, Poland. The Regenwurmlager is an extensive underground fortification area constructed by Germany in 1920s-1940s, now in western Poland, near the city of Międzyrzecz. (Photo by Anna Arinova/Caters News)

The combination of two different drawing styles in one picture never ceases to amaze us. The works of Allison Kunath are a vivid example of this technique. The background of her pictures is drawn using watercolors, while the actual image is broken down into rough geometrical shapes. This creates a very striking contrast, thanks to black, bold lines of the image on the forefront drawn over soft, cloudy shades of color. The skill of Allison is clearly seen in the way she manages to draw something as amorphous as a squid without making any curved lines. (Photo by Allison Kunath)

“Creepy crawlies have become stunning examples of the natural world in these incredible close-up pictures. Photographer Kutub Uddin, 28, snapped the tiny creatures in a forest near his home of Bognor Regis over the course of the summer. Taken in close-up using special macro lenses and filters, he managed to turn house flies, damsel flies and wasps into gorgeous jeweled works of art. Kutub said: “I found the bugs in the forest near where I live when I was taking pictures”. – Cater News

Nine years ago, Tom Carter traveled from San Francisco to China, responding to a job posting that turned out to be a scam. He managed to find another job as a teacher, and saved enough money to embark on a 56,000 km trip through all of China's 33 provinces that lasted two years. Carrying a camera – just a a 4-megapixel point-and-shoot – Carter captured some amazing images of the widely varying landscape, people, and architecture across the nation.

A replica of pre-historic drawings showing horses, rhinoceros and aurochs is seen on a wall during a press visit at the site of the Cavern of Pont-d'Arc project in Vallon Pont d'Arc April 8, 2015. The Cavern of Pont-d'Arc project is a replica of the pre-historic Decorated Cave of Pont-d'Arc known as Grotte Chauvet, in Vallon Pont-d'Arc in the Ardeche region, containing the world's earliest known art which was recently named a UNESCO World Heritage site. The facsimile cavern, which condenses some 8000m² of the original site into 3000m², will display faithful reproductions of paintings and engravings and will be inaugurated on April 10 and will open to the public on April 25.

Postcards for Ants is an ongoing painting project by Cape Town artist Lorraine Loots who has been creating a miniature painting every single day since January 1, 2013. The artist works with paint brushes, pencils, and bare eyes to render superbly detailed paintings scarcely larger than a small coin. After the first year, Loots relaunched the project in a second phase inspired by Cape Town’s designation as World Design Capital 2014.

Image patterning has existed for hundreds of years; however, before Thomas Yang no one has ever thought of putting paint on the bicycle wheels and using it as a patterning tool to create very interesting-looking pictures. Being an avid cyclist and an artist, Thomas Yang has decided to combine the two, creating the 100copies. The name of this project not only alludes to the fact that only one hundred copies of those pictures were going to be made, but also to the fact that the pictures themselves consist of hundreds of repeating shapes. And even though the project is called 100copies, no two pictures are alike due to the nature of their creation, making them truly unique. (Photo by Thomas Yang)
