....Especially if you're not good at it.
Some people draw their whole life and get very good around...let's say, ages ten or fifteen maybe? Between that or something. But anyway, I know why I lack skill in drawing and why it looks like a first grader had drawed it. (I know I spelt it wrong!)
When I was little I would draw pictures of what I wanted, or liked, or thought about..and you know what I'd draw? Stick figured cats.
I always wanted a cat, so I would draw one all the time I went to day-care when I was younger, and as I got a bit older I had interests in other stuff that didn't involve art - the SPCA! I wanted to be a vet and help ani
