the drawing. and of course the story line.

Mostly the drawing style or the story.

Probably the storyline and drawings.
Also, the title..

Mostly, and first of all its the drawing that actually gets me to start reading the series and then its the story. If I see a series with bad drawings then I would usually not read it, unless I hear really good things about it, then I would pick it up. But even if the drawing was the reason why I started to read the series, if the series is really dull, I'll drop it in a heartbeat

storyline and the drawings

its gotta be the art that sticks out, then they can get absored in the story ;]

It`s a picture book . I get tired of reading novels you know .

If I like the mangaka's illustration style, I usually take a look at it

boobies, panty shots, hek hek hek joke story of course but i cant help myself to like all shoujo hek hek hek sorry

Storyline & character design.

heh,....Its not a novel!

The part that gets me into it

I want a manga with a good plot...good looking ppl...good looking animations..something I've at least heard of once..or seen it multiple times...umm....and umm..if it's from the same mangaka from before...

But honestly I'm very picky about mangas and animes...which is sad in the end

The art, storyline and the leading characters.
