I can't get myself to sit down and draw 50 heads, hands, legs etc. I really need to but I haven't convinced myself that it'll actually help for some reason. I finish pieces every day involving dynamic poses, hands and feet, but I just dont churn out focused parts in mass. I end up studying the parts and only draw them a few times and move forward create a new piece again. Anyone here actually ever sit down and draw 50+ of something and realize that it helped greatly the next day?
