the best thing to do with any piece of writing is to get it reviewed/edited by outside sources so I guess you could always start with that?

Very excellent writers' guidelines. Very good reading for any writer.

The basics of what I do when I write anything, be it comic, story, game, whatever, is this.

For, I ask four questions. Who is the character? That is, the main character who the story follows. What are they, what do they look like, strengths/weaknesses, likes/dislikes, personality, that kinda thing. Then I ask, where is the character? What is the world like? Also includes approximate timeframe. In addition to this, I try to think of a world "gimmick". That is, something that sets this world apart from others. For example, in the book The Moons of Mirrodin, the entire world is made of metal (even living, organic things have metal "built in" to them). That's a good way to set the world apart from others, but if you can't think of one easily, don't force one.

After that, I ask who the character will meet along the way? Basically, the secondary characters, everyone important besides the hero/ine. Their loyal sidekick, the main villain, his henchmen, the shifty barkeep, everyone who will play some vital role to the story without stealing focus from the main character. Finally, what is the character trying to achieve? For this, I focus on two things - what the character thinks he is trying to achieve in the beginning, and what his goal is by the end. In many stories, the hero doesn't begin by knowing his goal. Maybe his original goal is to get the cute girl next door to go out with him, but by the end he must Save The World.

Once that's planned out, and this is the crucial and most relevant part - I list the story. That is, everything that will happen in the story, I write out in a list. Not every little detail, just the major parts. By doing this, you will know when you will get stuck in writing, and simply change a few things above the list to make you able to continue, instead of having to rewrite the whole thing.

The lis is just my personal method, though. It works well for me, but of course there are many other things you can do.

In my first draft of FreeFall Drift, I found that my main character had all the plot points of Luke Skywalker. I laughed. I cried. I did a significant rewrite!

But it worked for Eragon!

Except your parents aren't publishers I guess...

I had to laugh at that because you're right, Eragon sure did rip off Star Wars. I'm surprised no one's called them on it in public.

Anyway, to be on-topic, I think maybe these might help:

Hopefully, they help in some way.

It doesn't always work, but I just build the setting and let the characters carry it out by themselves. But that is how I write. I'm kind of a deist writer.

I have a really vivid imagination, so what I do is I go for long, meandering walks and just kind of "watch TV in my mind". Like, I just let things play out in my mind... that's how I generally decide the structure/pacing of a plot arc.
(for instance, there's this one scene coming up in the remote future, and I developed it a little more last night...) Then after that, I script it, edit, reread, and then let a friend of mine who knows what's going to happen in my comic read and give me pointers.

I think the main story-problems I see in webcomics are that they're either boring (like, "the aliens are invading, omg, look at that giant mecha robot thing... blah blah blah" ) or confusing (like, "who's that character again?" ) so as long as you try to make your comic's plot as understandable as possible, and steer clear from dry, kinda lame action scenes, then I think you're ok.

I glanced at your comic, btw, it looks really cool art-wise! I'll have to go back and read it~!

This is pretty much me as well. I used to have a script to go along with my pages, but after the fifth page or so i just started winging it. When doing a plot for my comic i basically ask myself:

-What's the character's goal?
-When/If completed, then what?
-What can i throw in the way to make the goal harder to reach?
-If this weren't my comic, would i be as interested and why?

With these, i can pretty much come up with plots, action, settings, etc. Just a thought, hope it helps.
