Is art level 85 to 90 feasible?

I have interacted with Google Gemini and I have found that my art level is 50 to 55.

The greats like Proko, Kim Jung Gi,  Rembert Montald,  David Finch are 95 to 100.

Can I reach 85 to 90 level ? This is the question I asked myself. 

I am interested in 1. Objects in front drawing.  2. Comics drawing.  3. Anatomy drawing. 

Luckily,  I have an analytical mind and have mapped my weaknesses.  They are

1. My perspective point changes over time when drawing an objectin front. Possibly I have fish eye problem and I need conscious correction.

2. Form making of shapes imagined or seen,  is weak. I have weaknesses in 3d carvings, 3d mannequins. I need practices. 

3. Shading. My shading is average and my shading need to speak. So to say. I need improvement. 

If I improve first ;5 points will rise. If I improve second ;10 points. And if I improve third; 20 points.

Then I shall reach 85 to 90.
