Now as I was saying in the beginning, whenever I take that same daily mindfulness and apply it to my art, I absolutely notice improvements, and usually much faster than naturally occurs. Of course if you practice anything long enough you will get better at it regardless of how consciously in-tune you are trying to be, but why not practice with intention and get better by leaps and bounds?!
The best way I have found to improve with intention is to be very specific where I am channelling that energy. I don't just tell myself, 'get better at drawing'. I would tell myself, 'get better at drawing hair', or more specifically, 'get better at drawing dreadlocks', then 'get better at drawing straight hair', and so on. Practicing your focal point is crucial of course, but practicing with intention by really concentrating on each line and referencing other artists' techniques or photos and doing it over and again until you get it right on every piece you work on will give you dramatically better results than just repeating steps alone or copying other artists. I find that trying to envision my desired effect before beginning each piece really helps to train your hand to create what's in your brain.
So for my most recent drawing-with-intention exercise, I have been trying to have a lighter touch with my charcoals and especially with the white chalk I use on the toned paper during the weekly figure drawing sessions I attend. When a subject is bathed in bright light, it's easy to record it as all the same value, however, fine-tuning and slight adjustments is what makes a good drawing into a great one. Usually I am a very careful drawer, but, alas, I am human and can get lazy from time to time so my intention is to be more sensitive all of the time because.....
One should never waste an opportunity to create beautiful art!
