I won't comment on the painting except to say I like the reflections.

I will say, it's tough to offer advice on a career choice based on a single example.
Showing a video of a good play at a high school basketball game and asking if a career in the NBA is worth pursuing is comparable.
The answer is always going to be 'maybe', but like others have said, as a lifelong hobby, the fine arts can be very fun and rewarding, just like weekly pickup games at the gym can be rewarding.

My story; I went to art school to learn graphic design. As a beginner I had some chops and I was offered a real paying job at the University printshop, but as I progressed, my artistic limitations started to become more and more apparent; however, I have good craftsmanship skills and I was able to transition to the production side of the business and wound up having a pretty decent career doing pre-press in the 4/C printing industry and later as a digital image editor using Photoshop.
