Oh I love that. It happened to me when I saw the art work of David Finch. I knew for a long time that I needed to add more detail to my art but I didn't fully grasp this until I saw his art. I buckled down and put more time into some of my more recent images and it payed off.
Well when your math teacher KNOWS you're improving, and sticks you into a directed study block that you shouldn't be in... Yeah, I'm stuck there now. And he adds stress against me, so I'm barely able to draw anymore without thinking of "MATH. WHY AM I IN DSB FOR IT?". [My art will never improve, since I'm horrid at it. xD]
I love when I wake up before my alarm clock, lay in bed, and come up with an amazing new craft project and finish it before my alarm goes off. This morning I made felt bows and wore the ivory colored one today.
