I see aspects of your current art style in this work. It's unfortunate that your parents wouldn't support you in your creative endeavors. I think all technical types need some sort of creative outlet.

I heard a theory, that people with technical mindset are one of the best painters actually, because engineric approach helps to answer questions "Will it work?" or "Is it possible?" in terms of anatomy, pose, lights and events happening on your pic. Also Engineric mindset obliges to google and read about objects you are going to draw before drawing them.
Also opposites tend to create a harmony :)

As for parents, they have seen a fall of USSR and tried to survive during that rough times. They saw how artists, musicians, even actors became pennyless, so they still have a mindset, that all creative people are very poor, drink a lot and live in a slums. But times have changed, art is completely different than it was in 1980s, digital art has been born and artists are needed everywhere (movies, games, boardgames, ads, etc).
But I don't see any point of proving something to the old people: they have their own lives. Most importantly, that we should focus on our dream and do the things we love to do, no matter what others say.
