You could try to inspire yourself from something like this. Search "Draw with Me" on Youtube. It's a 2D animation but that translates very well to manga drawings (assuming that's what you're doing). Plus it's a really cute story :').
Like, doing short stories without bubble texts. Hence, concentrating more on getting the pace right only with the panels and drawings in it, working on getting the right "camera angles" etc. Get a simple concept like that and pour everything on the art.
Sometimes when starting off people try to be too ambitious and get lost in getting into too much aspects, resulting in nothing being really that well done. But sometimes the simplest concepts end up being really beautiful, and then you develop your own style from there on :).
My two cents as an artist ;)
I need help.
Umm.... Right now I really want to draw but.....
I need ideas...
So please help me fill up ideas for a one short story....
A very simple punch!
I can only draw 4 pages once I feel like it though... (〜 ̄△ ̄)〜
But that being said, please give me an idea for a very simple one short story...
