How do you guys "study"?. It's been like a year since Ive last drawn and now I want to get serious with actually achieving the level of proficiency I can be happy with myself, but there's too much to learn, im going back to the basics and actually doing the whole "Dynamic Sketching with Peter Han" thing, then I will continue on with the sticky, but meanwhile I also downloaded several leg images and references because I suck at legs/feet, did a self portrait which sucked and then continued with my current drawing(pic related), but I have no knowdlege of color theory whatsoever so I was wondering if I should just make a mess of my current drawing and "finish" it to practice, or wait until im done with tutorials of fundamentals on coloring. Do you guys just stick to one subject and grind it until you are happy with that or study and dip your toes on subjects you are still not studying?
