At the end of the day, nothing is easy, even when you're used to doing a particular activity. With each new project, new difficulties almost always arise.
But if not, other than that, did you want to create a comic strip or is it just out of curiosity?
And as for me, for my part I followed ... taking into account my irregular work rhythm, the advice of an old site of an association teaching young people to create comics. And among the tips and tricks they provided, they provided a working method to build a comic strip consisting of first finding the fall before the start and the middle of the joke.
This technique is called the reverse gag, and has been used by the big names of Franco-Belgian comics (and I suppose in America and Asia too, the proof precisely with the Yonkoma) and is still by comic artists .
Once you have found the fall, you will just have to go back to the course of the action by looking for what caused this situation, how everything to start to get there.
Then, the general organization for making the comic strip will differ slightly from what you would have had for a longer comic strip, I think? Because I only do comic strips, so I have no experience in terms of long history.
On the other hand, when I speak of organization, I mean this:
1.Writing the story (takes a lot of time. To find the fall of the joke and how to bring it smoothly to the reader without rushing. Sometimes I even start already visualized the segmentation of the boxes / sequences / shots of the scenario)
2.Do graphic research if necessary, in addition to literature research to write the story. (this part is not very important for me, I forget it altogether. So the design ... or rather my level in drawing, is sketchy)
3.Write the screenplay (like I said, I tend to write the story and the screenplay at the same time. To do this, I just need to have some semblance of a synopsis or summary to work with)
4.Staging the comic strips using storyboard (s) (similarly, the storyboard (s) are closely linked to the scenario so they are worked on and pofin for weeks or even months.)
(then, it's just a matter of tidying everything up by building the final product, not forgetting the next ones, like ... as far as the episode cover is concerned. But that does not prevent us from having
last minute unforeseen events requiring changing two or three things in the scenario)
5.Make the sketches of the final panels (lineart, etc)
6.And inked it all
