Supergirl and Cityscapes

Here is a really quick drawing sketch that I did of Supergirl flying over the city. I hope u guys realize that it is all done free hand and without the aid of any drawing tools or rulers. Clearly, all of the buildings are sloppy looking and not straight with each other. But I liked drawing this picture anyways to practice drawing cityscapes more. It was difficult and I tried to even use a grid to aid me in the buildings, but I was not able to do it on freehand alone. If nothing else, it is a good example of what happens when you try to draw stuff without a ruler.
