Being tall may give you a natural ability to play basketball. But I’m not convinced that being good at drawing requires a unique physical or mental attribute.
If you’re born with a healthy brain then there’s no reason why you can’t become very skllled at drawing. And like anything - the younger you start the better you’re likely to become.
The people that think they’re gifted at drawing probably just started drawing early in life. My drawing abilities decreased considerably later in life because I lost interest and practiced drawing less. Yet I know people that thought I was gifted with drawing abilities when I was a child. I wasn’t at all. I just used to get into trouble a lot and was grounded quite often. So I would simply doodle to pass the time away.
I would also spend most of my time at the back of class doodling on my books while the rest of the kids learnt about algebra and Henry VIII.
I predict in future that there’ll be far fewer kids that have drawing skills, because these days when kids are grounded they go play on their XBox’s!.
I have several nieces and nephews and they couldn’t draw to save their lives.
