I can only talk standing at my current skill level.
It will take 1 year of hard practice and structural training.
If you are in a range of 850 - 930, producing consistent works, you are pro.
Now you have to draw things that need to be drawn, not what you like.
That will create slow growth.
I have seen portfolios in ArtStation where they start at 900 and 10 years later are still 900.
They are rare, talented people.
But their talent is their obstruction.
Right now when I am learning to draw, it is becoming more and more difficult.
How difficult is it?
It is really difficult now.
like a 7/10 difficulty.
That difficulty level is going to increase after 6 months.
Now my range is around 700 to 800.
I can confidently bet on that.
Some of my paintings have gone far, passing the 850 range.
But I am not producing consistent works in the 850 range now.
When you produce 850 consistently, some artworks may push to 930 and above.
That is the truth.
Now, how does a 950 +art looks like.
Like the images of Feng Zhu. FZD school of art founder.
The technicality of all his images is exceptional.
Do I like his art?
No. But it doesn't matter whether I like it or not. It is top-notch.
I like someone like Simon Stålenhag and Bekinski.
