About a month ago, I was trying to draw an angel sculpture that we have in the yard. The drawing went south really quick and I gave up on it. I tried again to draw the angel today and found that my skill levels increased over the past month. Progress isn't a straight line, but you can often find spurts where you progress fast.
As embarrassed as I am with my first attempt at drawing, I'll show the picture so you can see what I mean.
