I am going to skip the preamble for a moment and get to the point:
You know when you draw a girl and she looks great and you're about to put it up on DA when you notice that.... she's got no clothes on, her expressions are suggestive and what are those things grabbing her?
Back to the preamble:
I am an occasional artist, as vague as that is. I draw when I get inspired, however I don't plan on making art my life source, partially because I am an amateur at it. Though I have noticed that all my troubles with proportion, expression and interest are like a plague when I draw normally and out the window when it's about that 'special something'.
