So art school was totally useless

The only reason that I can't say I'm self Taught Is because I did 5 years of art school. At that time I (we) understand nothing about drawing.
This is how I drew 10 years after art school:

I didn't knew anything about drawing. Teacher didn't told us how to see, they just told us how to draw proportions.

This is now

I still need to improve, I can't draw right from my mind (Lately the only thing I draw from mind are hands, just because I'm too lazy to find photo references. And anyway I look to my hands), but, 99% of things I know about drawing was learn in those last 5 years.
