You have a calculative mind and keen observation skills along with artistic abilities.

Fine arts would be suitable to you to a moderate extent as a career. The proficiency in fine arts could take a few years. Thus you can continue and be in touch, practice, develop and master your interests, so that you can take them also as your career along with your other career and singing can be your secondary skill which you can gradually develop and master.

This way you will always have more than one career, which will not only benefit you financially but give a personal satisfaction of achievements. Be positive and go ahead with your interest.

Best Wishes.
