Your art is original, it may be a source of constant income and consequently, it needs protection from infringements. The Copyright Law in India states that the owner of the original copyright/subject matter needs to register with the Copyright Office in India because it gives legal protection against infringers and other notorious copyright violators.
The work must be original. The terms of copyright protection vary consistently with the type of artwork that is created. The term may extend the protection for the entire life of the creator and 60 years beyond that. A procedure of granting a Copyright in India starts with the filing of a copyright application in the Copyright office.
