Well, there goes my advice o.o
I only feel the need to defend my opinion on the narrative. Mainly because, while you can keep it honest and about real life, there's a difference between having it be relatable kind of angry and just uncomfortably personal. It's more like you should keep a comic diary in that case, something that can be used to express anger but stay unknown. Imagine if the girl you were talking about came across this comic. I dunno, I suppose there are people that enjoy that but, that may just be my opinion.
Sorry, listen to the other people, disregard what I said. They know what they're talking about.
I think you have a valid point. While honesty is important in an autobiographical comic, it's still a comic that's out there for people to read. Like any comic, you (hypothetical you/the author) need to decide whether your goal is to just do what you want to do, or to make something that appeals to readers. If you just want to do a diary-type comic and don't care about appealing to readers, then any tone works, but it might be best to keep it private. If you choose not to, don't be surprised if very few people stick around for it.
If you do want to appeal to people, then you need to treat it a bit like fiction - dramatise, pace the serious and comedic moments so that the reader is not overwhelmed, keep it interesting. Autobiographies are usually not the whole truth, they're embellished to make a point, and to keep the reader interested.
Another factor is the author's enjoyment - for some people, documenting the truth/their opinion of the truth is the most fun option. For others, making an interesting story out of the truth is more fun.
As for art - I think it's important to develop one's taste by looking at other people's art and figuring out what you like about it, and
why. It's a bad idea to ape someone else's style or someone's way of drawing (whatever), but there's nothing wrong with, say, liking the way someone draws noses, figuring out how/why they stylise them the way they do, and applying a similar stylisation to your own understanding of noses. The result will still be your own style, and you'll develop a greater understanding of both the specific subject and stylisation in general.
