I'm so impatient. I had the time to work on this after a long absence, and I got bored in the first 10 minutes. But, instead of giving up altogether, I decided it was time for the buildings in the background. And yes, here I used vector shapes and gradient fills to create the base. I figured that it's pointless trying to draw a straight line by hand on a computer. Mike and Leo would agree, I'm sure :)
Now I'm excited all over again!
