Art Drawing

When I've checked my drawing, I check again. I have to nail down its underpinnings before I can add details. I really avoid guessing at the details; I want to make sure things are symmetrical and look right before putting down stronger and harder lines. I constantly ask myself, does this feel right? If anything seems off – even if I can't immediately put my finger on what it is – I trust my gut and troubleshoot my drawing before continuing.
