Didn't know it but at 7 years old I was a Artist didn't know it then ,But I'm a Artist.
Medium has nothing to do with being a Artist.
It's burned in to your soul ,rather you want it there or not,like love.

I might get nostalgic for the old days ,from time to time.

But to do one oil painting at least $200.
cavus ,brushes ,linseed oil ,etc etc.
one tube of red can cost $50.
ya need a lot of space ,hole room.
You get lead poisoning.

Air Brush ya need the airbrush and compressor.there not cheep.
a lot of masking.
alt to have a paint both ,good mask ,well ventilated space.
ya still breath the paint.

So now you have gone threw all that.
Who sees ya Art ?
Can't copy it .
You can give it away to a gallery if they want it.
Some gallerys keep 90% of sells.

CGI is more affordable and a lot safer.
CGI is a better medium ,you have never seen what zBrush has done.
You can show the hole world ya Art :)

============================================================ 

The Artist that will fight for decades to conquer their media.
Even if you never know their name ,your know their Art.
