This is a tough one, I mean, I can be overly critical and hate how some pages or panels turn out, but over all I like my comics, I would not work on them if I did not like them even a little bit, so that being said, if I didn't draw my comic, but found my comic (that was made by someone else) I would be a fan of it, because I make comics about stories that would be interesting to me, with characters that would be interesting to me, just like anything else I'm a fan of that has a story and or characters that I like.
Actually now that I think about it, I would actually probably advertize 'not my comic' more than I I actually advertize 'my comic'... cause that is currently what I always do with things I like.
Person: Hey you draw a webcomic?
Me: Yes, but speaking of webcomics have you seen 'Lackadaisy' ahhhh maaaiii gaaaaawwwwwddd Hold one. Lemme find the link, cause I'm going to show it to you right now.
Person: Do you have a link to your comic?
Me: Yes. Yes I do. But we'll get to that later, for now you're reading this, Look. Look at it. CLICK THE LINK!! CLICK. THE. LINK! I Need you to like this like I do, you don't understand... I need more Viktor and Mordecai fans to associate with.
Person: Wh-
Me: LINK!! CLICK IT!!
See... that would be me with my comic in another world where my comic wasn't my comic but the comic of someone else... you get the idea.
Would you read it? Yes I would, it has stories and characters that I like, it would be hard for me not to if I managed to discover it.
What would be the first hook that grabs your attention, writing-wise? That's hard to say, different things for different stories manage to hook me. I guess the characters would be what would appeal to me the most. I tend to create a lot of characters that relate or WOULD appeal to me, so it's hard to think that I wouldn't like them if I found them somewhere else.
What would be your favorite thing about it? Another difficult question, because that's even hard for me to answer for things I like in general "what do you like about 'anime series" Me: Well, I hate the art style sometime but I would have to say I love everything. "What do you like about 'game title" Me: Well I really hate the thing but overall I think I would have to say I like the everything. "What do you like about cats?" Me: Well that would have to be their everything.
But for the sake of attempting to answer this question... umm... I would like... that I liked it and was enjoying it...?
What would be your least favorite aspect? The spelling and grammar mistakes, and if the author is anything like me the random hiatus and wait time from them constantly getting sick and getting themselves in the hospital. And some of that art man, who ever drew my 'not my comic' better be like 12 years old because wtf.
