Am I practicing wrong or right?

Hmmm, that is true, but I still think that if you look at drawings from those kind of people from one year to the next, there's probably some kind of improvement, no matter how minimal. Will they improved any usable skills? Probably not. Will they get a job in the industry at that rate? Probably not. But it's still improvement. That was me for the first few years of drawing when I was in high school, but I did still improve some.

True, one will invariably get better at producing one's own idiosyncratic mistakes. They'll get more polished, if you will, and certain purely technical skills may also get better through sheer repetition.

But that's not what most people are really after, which is where I was coming from.
