This one is a tricky study, the way the shirt falls on the chest and all is making it hard for me to figure out the colros and proper accent even though i got the ref next to it. I wanna make sure i'm able to properly understand what i have in front of, if i don't then it's not a study lol.
If you study any type of picture, don't use it as a crutch, actually try to understand what you're doing and what the purpose of each stroke is. Some might not be clear when you first start out, but eventually with enough mileage it will. It will for as long as you STUDY and don't COPY.
