/ic/ - Artwork/Critique

after going through keys to drawing and perspective made easy,im lost on what to do. I figured out that im a grind-a'holic. Exp per hour was my shit in vidya and realised i learn anything the same. I have to grind out something a shit ton. Im try to nuke a sketchbook per study type. book on hands and another on cars. shit like that. Im just not sure what to focus on or have a few sketchbooks dedicated to. I would even work a small sketchbook per excersize in the books i already have. i just dont want to waste time. Any ideas where a beginner should focus on and start making a check list to reach internediate level.
