If you think you have the talent and enthusiasm to become a pro artist, you should go ahead with it. However, do remember that talent alone won’t take you anywhere unless you can imbibe discipline into your routine and pledge to improvise over your flaws. Modern decorative art painting is more about observation and diligence than anything else. However, some educational or technical qualification also helps.Though you can sign up for some course if you wish, the best form of learning is self-education. Research as much as possible, observe the paintings of artists from all eras and try to experiment with different styles. When you are working on modern wall art paintings, you will produce bad work more often than good work. It is the part and parcel of an artist’s life. Don’t let your failings curb your enthusiasm; keep on improvising and producing work until you come with perfect art.Warming up is also essential. Your first few strokes of brush may not produce good results. Allow yourself some time to get into stride and after an hour or so you will feel confident as you slip into the right mood. Contemporary canvas art work also requires a professional to be discreet with his materials.Since you are aiming to become a professional artist (and not just an amateurish one), you must not work with shoddy materials! Even if you have to invest some extra bucks, make sure that your painting brush, canvas and colors are of professional quality.Out of the 10 paintings you produce, 7 or 8 (or even 9) may be mediocre stuff. Do not throw them away. Stack them for future reference, but do not market them or show them to a potential employer. Quality should be given precedence over quantity. Display only those works which are your best.Your hand-painted art paintings will require you to choose from a gamut of media and painting styles. As for painting, you can choose to paint in oil or in acrylics or you may use watercolor. Watercolor is the cheapest but is preferable mostly for landscapes or seascapes. For portraits and decorative art paintings, you better settle for oil painting or acrylic painting.You must also learn about computer imaging. The modern artworks take assistance from computer tools and software especially for illustration. You can help yourself grow and get better in art by teaching novices or young learners. Also, try to improve your power of discernment, develop your power of judgment, learn to take negative comments in your stride and try to tell a story using your art.
