Ken Garduno, from Los Angeles, California, is amazing at his craft. But instead of showing his final, polished pieces, we want to highlight his more rough sketches.

Sometimes you need nothing more than some black ink and a sheet of paper (and possibly Ken's hand). The line is a beautiful thing.

I'm a longtime fan of David Shillinglaw's art. It's impossible not to be. He's got great instinct when it comes to letters, layers, shapes and colors, and wait until you see what he can do on a concrete wall.

If you've never taken a marker or paint brush to a wall, get off your butt and make it happen this weekend. You must, if simply for the challenge when it comes to size and scale. It's by far my favorite canvas and no one does it better than David.

Below are some of my favorite of his images (including a video of his process).

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.

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?

I don't know if I envy Eric Olmstead more for his insane talent or his extensive travels. His work is so vivid in color and detail, so powerful in narrative, and so pop art and animated, I almost expected a few onomatopoeias: POW! CRRACK! WHAM! KER-SPLASH! From being drugged and robbed in Ecuador to finding himself in Sydney to backpacking in the Philippines, Eric's artwork brings you with, so you can imagine hiking the Inca trail alongside. For anyone bitten by the travel bug, you know that Wanderlust always calls. Eric Olmstead answered.

Aitch, an illustrator from Bucharest (suddenly I realize that I've recently only been talking about female artists)… describes her work as "ranges from pink, cute, elegant, to sometimes creepy, semi religious, bizarre characters, mixed in surrealistic sets" and I can't agree more. It's amazing how she moves from the "cute & pink" to the "surreal & semi-religious".



She normally works on paper, toys, urban objects, and many shops around Europe. She's one of my latest discoveries (and one of my favourites!).

I follow her on Facebook where the talks about her illustrated life.
