Applying for your dream job should not be limited by your previous experience. In arts your experience easily translates from one medium into another. Think of the experience you do have and how it can be helpful in the position you are applying for. For example, if you have experience painting on ceramic mugs, but are applying to a company that designs clothing with graffiti elements, you can still highlight skills that make you a good match for the job, even if it's not exactly the type of painting you’ve done before. If you are lacking in professional experience, focus on skills, education and certifications to show your credibility as a professional artist.
