The Flash comic has indeed been cancelled. It might be due to various reasons such as low sales, changes in creative direction, or the publisher's strategic decisions.
The comic Flash typically has more established feats of speed compared to the DCEU version. However, different versions and story arcs can sometimes make the comparison less straightforward.
I'd also recommend 'Flash by Mark Waid'. His run on the Flash comics was really popular. It had a lot of fun and fast - paced stories that showed off the Flash's powers and his heroic nature. It's full of exciting adventures that new readers would enjoy.
Well, it's not straightforward to say. Different comics might portray their speeds differently based on the plot and creative decisions. So, it varies.
First, come up with a good story idea. Then, learn the basics of drawing and animation. Use tools like Adobe Flash or other similar software to bring your ideas to life. It takes time and practice.
