Here's a tip when your making a comic, it doesn't have to be a long adventure, just a few panels or a funny joke to model. First, just choose some interesting characters that you think could really make people laugh.
After all that's what comics are for, to be funny.Then draw the backround. Make sure it makes sense and is appropiate to your story. Also, try to set the mood of it, like if your character is sad, try to match his feelings in the backround.
Then it's the fun part. You should have fun with it, and add any extra items or effects. Once you do that and you like how your comic looks, your done! Wasn't that easy?!
Anyways, now that your done, you should share your comic with other people (as long as you don't mind some people copying your characters.)
*Tip: You can do it on your computer too, just follow the same steps and use a software (like paint, etc.) to use.
