This was a quickie Flash picture I think I drew after watching an episode of The Flash. The main thing that I was trying to do differently is draw more smoke clouds following behind the Flash. I think the smoke typically makes a picture look cooler looking. And the other thing about smoke is that it is quite easy to draw. The trick is making more clouds the closer it is to the source and less clouds the higher they are.
However, with this picture, I am not even sure what the smoke cloud is doing in the background. Is the Flash speeding away so fast that it leaves a smoke trail? Or is he running away from an explosion? Unfortunately, I did not draw it so clearly.
