There are a few questions we get pretty often in regards to the 50% rule, so let's clarify them right off the bat.
Should I be trying to apply the techniques from Drawabox while working on the 50% rule?
No. Draw in whatever way feels most comfortable to you. Drawabox is designed to have you drawing so much that you will have plenty of mileage to take the lessons and push them down into your subconscious. The lessons will become instinct. Rather, as you play, it’s better not to be too stiff and worried about technique. This is the time where you want to just let go.
Do I have to do my 50% rule in pen?
No. Draw with whatever tools you’re interested in using. A lot of students come to Drawabox really interested in digital media, but end up disappointed that we focus so much on traditional tools. I get it — I’m almost strictly a digital artist myself — and we’ll get into the reasoning for this later. Rest assured though, you are welcome and even encouraged to dive straight into drawing and painting digitally as soon as you like, for this 50%. This will also have the benefit of helping you get used to the specifics of using those tools, as this is yet another skill that is separate from these core fundamentals of drawing, and will need to be explored at some point.
Can I use reference during the 50% rule time?
Like everything else with this rule, it comes back to your intent. Are you reaching for reference because you're afraid of drawing something inaccurately, or wrong? If the motivation behind it is fear, then no. Face your fear, draw it without reference.
If however you wouldn't have any issue drawing without the reference, and are just looking to have more tools at your disposal to play with, then go for it. Just make sure that what you're drawing is not in its entirety, just a copy of a reference image. That would be a study, and would fall into the study portion of the 50% rule.
A good strategy is to first roughly sketch out your idea without reference, so you're forced to make all the decisions as to what goes where, how it's laid out, and so forth. Then, using this sketch, find suitable reference and then redraw it. This will help ensure that the reference itself is not deciding for you what you should be drawing. The control should be in your hands, and the choices should be yours.
At the end of the day, there is nothing wrong with using reference in general — what the 50% rule focuses on however is breaking down the barriers we put in our way because we're afraid, because we're anxious, and because we don't want to make mistakes.
Where do portfolio pieces fit into the 50% rule?
The things we draw will generally fall into one of three categories. Practice, Play, and Performance. Technically a single drawing activity might fall into multiple categories, or even all three — but the more we spread it out, the less effective that activity is at accomplishing the intent of any one.
The 50% rule addresses practice and play, but we leave performance out for the simple reason that most of our students are beginners, and so most of them aren't really in a position to be concerned with it. Performance is all about showing where our skills are right now, and beginners are understandably lacking in those skills to show off. We certainly don't want to give them the impression that they're supposed to come already equipped with skills.
If however you're one of those students who's filling in holes in your fundamentals and want to spend time producing work that shows where your skills are right now, then how you work it in is up to you. You can choose to split the 50% rule into three chunks of 33%, or you can do 50% for play, and split the rest up for your studies. I leave it up to you, as long as you strive to hold to the spirit of the rule.
