Social Media: Facebook remains the largest most influential social media monster out there. Besides having your personal page for family and friends, create an artist page for yourself with a good amount of art samples for your gallery which will serve as your portfolio. Connect this profile to your Instagram account...you should have an Instagram account if your an artist. Communicate daily or at a minimum every few days with either art or updates on your latest project.Business cards: You have to have them. You can get them for a good price off of Vista prints. They are a must. Everyone you meet that is somewhat interested in what you do or would like to work with you will appreciate a business card. At the end of the day you are a salesman selling your service or product.
Networking: Oh yes...here's the part so many dread. You need to go out and socialize. Many artist are very introverted so this can play a particular challenge. Go to comic book stores and comic conventions. How to engage in a conversation: Start off with a nice complement (comic art related works well) and smile. Then follow up with an introduction... "Hi, my name is Andres. I draw comics." Have your portfolio with you. Try to avoid showing them your online portfolio on your phone and try to get them to use theirs in order for them to like or follow you.Small Jobs: Take on small projects to get your name out. You can look into magazines for quick 3-10 page projects. There are also small indie publishers that you can work with but don't expect much money out of it. You can also go for the Mid-Level publishers. This will help build up your reputation. Its good practice on meeting deadlines and meeting editors.
Remember to place your art out there one way or another on a daily routine so that it becomes a habit.
