A good painter creates art on a regular basis and explores painting with various mediums, as well as experimenting with other creative materials, such as clay. Trying new skills and techniques is important for a painter to develop his abilities and discover his strengths.
Being a good painter does not require a formal education, but it is helpful for learning about art history and classical techniques. Many painters improve their skills and discover new areas of art they enjoy. Formal education also exposes a painter to constructive criticism and provides opportunities to show personal work or enter competitions. In addition to art classes, many colleges and universities have business and marketing classes that can help an artist learn more about promoting his work and creating a brand.
Collaborating with other artists is another way for a painter to improve his work. Putting together joint shows or sharing studio space exposes a painter to other types of work and allows him to ask questions about techniques or tools that other artists use, expanding his repertoire in the process. Networking with local businesses shows an artist which of his paintings or styles is in greater demand. Once a painter has reached a high level of expertise, he can apply his knowledge to teaching other artists.
