Hey, you're going to grow as real artist now won't you?

I had a look at them:
-/ Jack's Life: I like that you use storys from the normal life, go shopping normal stuff and that.
In the second one some random things are happening without a "real" connection, I suggest to use a "red line" of story, a main theme that dominates at least 80% of the story.
Art:
Nah, you need more professional speech bubbles, please have a look at marvel comics or any other professional template. Yours look pretty cheap from the computer, but that just might be my personal standards of quality that make me want to complain
I like this one; its just a image but it has strong expressin and tells a whole story, well done!

-/ Myths & Legends : Erghana
Oh I'm a big fan of stories with a female kickass protagonist, thats for example the reason why I chose a female one in Fallout 3 or Mass Effect 2. But I don't like your style of drawing, its too abstract for my taste.
My suggestion is that you get yourself a learnbook that teaches how to draw in Manga style, which is graphically very strong.
And additionally a artist book to learn the correct anatomy proportions, but in the correct angle of the image viewpoint.
- / The Pirates Paradise
Pirates + Scify = Coooolz
The gif comics look really awesome, love it!
I also love the idea of the "red button", funny and effectfull.
Blob blob blob ? and then Pang Pang boom? - You made my day ^^
Why do you have to make 3 different comics?
Diversity is good, but that splits your working power into 3 parts, you could concentrate to do a really strong flaggship comic if you decide to do only one of them for a while.
