I want to introduce you to one of my favorite illustration projects of late. It comes to us from Israeli artist, Geffen Refaeli. The concept is incredibly simple, and the result, flawless.

What started as a personal experiment to practice drawing and doodling has turned into a daily art project with over 20,000 followers (in under a year). Every day, Geffen uploads an illustration that was inspired by a mashup of her friends photographs. She takes bits and pieces from their pictures and creates one-color, surreal drawings. She then posts the drawings on Instagram (@dailydoodlegram) with links to the photo feeds that prompted it all to begin with.

I'm a fan, and I'd gamble to say so will you be. Prints are available at her recently launched shop.

I'm absolutely awe-struck by the sheer size of the Doodlers Anonymous group that lives on Flickr. Launched in November 2008, the group now houses over 34,000 drawings, doodles, sketches, scribbles, paintings and so much more.

It's a treasure of inspiration.

We do our best to consistently moderate the group and dig around for awesome finds. Images above by Jeannine Ortiz, Mary Ruth Patchin, Maura Cluthe and below are some more favorites. If you're a friend of DA, you'd be crazy not to join the group… You simply never know when you might just find your art featured here on the blog.

I love that Anke describes her sketchbooks as "everyday training." It's exactly on-point, as she uses them to practice her craft and quickly capture a moment of everyday life, page after page.

Beyond her sketchbook pages, what I like most about her work are the drawings on different papers that layer to form a perfect design and final illustration.

Ben likes to draw buildings on fire, space objects from our favorite movies and often times quirky celebrity portraits. Here are some of my favorite by him and I think he's captured their expressions quite magnificently. Can you name all six popular heads in the comments below?

Born in Moscow, brought up in Milwaukee, and now based in Manhattan, Sonya Kozlova (at the early age of twenty) is known for her photography. Her photos are experimental and visceral, and it's obvious she has a keen eye for lighting and cropping her subjects just right.

She's recently mustered up the courage to share a few of her sketchbook drawings and they've captured my attention as much as her camera pictures have. Here are a few of my favorite pages.

Miguel Herranz (aka freehand) is an Urban Sketcher with an incredibly detailed hand and a complementary story to go along with each sketch. The stories range from memories to the people, places and things he comes across. Below is a snippet of his text for the drawing above:

"…I keep on drawing... I wonder what happens behind the third window of the second floor on that brick building... I imagine a filter that tells me with some color the places where people laugh joyfully, with some other color where they shout angrily, with other where they make love, where someone just died... I know I'm drawing all this."

It's a must that you take the time to read the captions behind each drawing. You will fall in love not only with his skilled hand, but how he describes what he sees.

Krysthopher Woods often turns the ghastly and creepy into stunning and sublime. In the third wallpaper from our series, he seems to have drawn a creature enveloped by snow and tears during it's final journey.

It renders beautiful and it's yours to download.
