Ugh yeah, lots of frustration and ripping out my hair. I still do that now, but man I was particularity angsty between 2011 and 2013.
I havent been formally enrolled into a full time school but I did take a brief class on Saturdays about Observational Drawing near the end of 2012. The teacher was ridiculously amazing at drawing what he saw, so I learned several good tips from him
Lots of practice and study (i have hundreds of DA tutorials in a folder o.O) is really what helped me overall. As I got better it became easier to understand the concepts he had tried to teach me.
