I started this Project Sketchbook from the second week of September, 2014, to pick up what I missed from undergrad. As an industrial designer, I haven't had enough training and practice in portrait drawing and airbrushing, which I find it's dragging me back somehow.
Anyway, so far it's my second week deep into this. I started as "breakfast sketch", meaning it took me 30-40 minutes, aka, a good breakfast time, to draw a quick sketch on the paper. Then I did more airbrush work and moved everything digital, to Sketchbook Pro, mainly.
Week 1
Week 2
Week 6 (it's been a while)
Week 7 was dedicated to shoe sketch. It took me a while to figure out the details. More to come (in a comparatively shorter time, I hope).
Week 8. Continuing on shoe sketches.
