Hi Aspirant,

There are a lots of online fine arts courses that you can pursue. You can just visit the online platforms like Coursera, Edx, etc., to get the course of your interest and whatever is best suitable for you. There is also one famous course of fine arts offered by  Indira Gandhi National Open University (IGNOU) via Swayam. It is a 12 weeks course provided in online mode. Here you will also be certified by IGNOU for the course received. Now the success of online courses depends on how you pursue it. You can also apply for some internship as you get some some experience through the course to get the most out of a course.
