Get your name and work known locally. Attend local art shows, interact with other artists and ask them whether they would like to see your work. Get their contact information and send them some of your drawings. Ask them to provide you with feedback and useful advice on how to proceed in getting published. Get as many people as you can to see your pencil art and make sure they remember your name.
Attend as many pencil art seminars as you can. Be active in art groups that support pencil art and go to all the seminars or meetings that they organize. Get to know artists in your specialty and find out how they go about selling their art to publishers. Interact, accept feedback and keep an open mind.
Keep researching your market. Make sure you always know what is selling and who your target audience is. Publishers are more likely to accept your work for their books, magazines or newspapers, if it is on a subject that sells. Also, knowing your target audience, even if it is an exclusive one, means that you need to promote your art even further before you start sending query letters to publishers.
Make digital copies of your work and publish them online. Take photos of your most unique pieces of pencil art and upload them onto your computer. Build a professional website and display your work. Share your photos on social networking websites and try to get yourself noticed.
Contact potential publishers. Write a query letter, asking pencil art publishers whether they would like to see your work. Tell them about yourself, show them your work, attach links to more samples of your art online and kindly ask for feedback. Accept criticism and do not get discouraged if they reject you. This is a competitive business but if you keep trying you will get your pencil art recognized.
