What do you mean? I'm slightly confused.

and now?

Uhh still a little confusing. Are you talking about someone criticizing your own work for a R34 art or something that you did yourself??? And it's irking you, or are you talking about yourself going into another artists comic and wanting to make art of their character. It's a little confusing.

you dont know what a fan art is?

I think he means he wants to post fan art for the comic that he likes and in the Artist's Description box there would be a rant about the comic.

O..o a tad confusing indeed, not sure how the two are related.

and now?

Uhh... well... you can do that if you want to. If you're a fan, you have a right to rant about the comic while presenting fan art. I'd probably do the same. x3

I know but since I'm very emotional I can get it too far x3

Ya gotta express what grinds yer gears! x3

So what you mean is:
*You like a character in an adult comic.
*You want to do fan art of said character.
*You have criticisms about the comic and wish to rant about it.
*You are afraid to write said rant - because - you want wish to make fan art of a character.
*You feel conflicted because of these problems.

Right?

Yes and begin attacked by a bunch of angry penises (if you know what i mean).

Well if you are afraid that ranting will cause some backlash, I'd advise to not rant. Perhaps try and give your concerns a little more constructively, while also telling him/her what you like about the comic.

naa it's pointless plus he is Japanese so he will not understand or care as long he win money.

Lol

Then again it is likely that whomever it may be does understand English writing even if barely.

But still I doubt someone like him will listen to someone like me. XD

I say ignore what the guy rants about
it's ur art, ur choice. if they get angry about it
then maybe they should do the drawing themselves and see what it is like
don't fall into that fear
