I think that part of your problem is that you assume that parodies have to be stupid. This isn't the case.
Also, it may just be that in its current form your idea simply doesn't work. I'm pretty sure you remember how well it went over when you tried to launch it here the first time. Perhaps you should simply dump the idea and come up with something new.
Just because it's a parody doesn't mean it has to be stupid. in fact, parodies that have a modicum of intelligence tend to be infinity better than just saying" Oh look at this! It was one thing and I'm making fun of it now. I'm funny right?".
You actually have quite a few pageviews for someone who's only been here a year. I dunno what you have to complain about as long as people are seeing your artwork.
I understand if everyone is giving you shit over your art though. It is YOUR art so you can draw whatever you want (long as it's not against the rules of course, but it's not). Plus if you clearly said they're parodies, then people are just being dicks on purpose But yeah, you got yourself quite an audience, you're lucky.
A parody isn't necessarily supposed to be stupid, and that assumption may be the problem. I'm not sure what the creatures are supposed to be parodies of.
