It always happens. I come home full of desire to be artistic but life gets in the way (and currently Star Trek TNG marathons) and so I head to bed and pull out my night stand sketchbook and draw. Right before bed. Right around midnight. I want to remember that incessant desire to draw I had back in HS. Did too many years of art schools wipe that desire out? Or is it because I've learned other techniques and realized that three dimensionality is my prefered medium, drawing feels cumbersome and to flat? No matter what you always start with a sketch so I must suck it up and continue drawing.
Always learning. Always improving (one hopes). You keep trucking away. Enjoy.
