Hmmmm, nothing super weird is jumping out at me...I always have a sketchbook on hand or close by. Sometimes I will drop everything I'm doing to sketch an idea I suddenly had, because I have the memory of a goldfish. I keep a messy space, which drives my dad nuts, though I'm trying to get better about it. I just like to feel comfortable and have my stuff on hand at the ready.
The weirdest thing I can think of is my tendency to stare. If I'm drawing something, or plan to draw something later, I stare at whatever it is, analyzing every curve and line. No biggie when I'm looking at a source photo, but it can be awkward when drawing inspiration from life. I am doing a portrait for my best friend, and was studying her arm tattoo for reference, and she actually called me out on it (its a present so I couldn't explain, which made it worse lol)
