Let's not forget, that talent alone is not the way to a good artwork. It is only the basis. Talent makes roughly 5% of good graphic work.
The rest is years of continuous learning and training in drawing, painting, typography, calligraphy, programs and input devices.
It's also the knowledge of choosing the right tools for each project.

But on the other hand, I have to say, that a complex and completely hand drawn and hand written map without mistakes is yet a sign of extreme mastery.
Clicking on readymade icons in applications and taking back every step is not what I would call high expertise in mapmaking.
That's like putting a frozen pizza into the oven and call it cooking.

In the end, a computer made map may be a very good piece of work. But a hand drawn, written and colored original is a piece of art.
Just my 2 cents.
