Well I was going to say this when I officalize everything but who cares.
I was going to say that you could incorperate Halloween into the picture. Since it is a fall holiday, and it could do something like in the criteria that I'm going to post, so it will happen. So now if you are going to participate when I am ready to put up everything, you may use a Halloween theme in it, but it has to be based on fall and dreams/fantasies.
NO HENTAI FANTASIES!!!!!!!!
This is purely based upon the fact that I thought it would be a very neat idea to mix all the magical or anime fantasies with fall to make a cool event. So go ahead make your people summon a huge monster for Halloween as long as I see that its fall oriented.
Oh as a side note, nothing really badly grotesque, evil, dark, or depressing. You can do something to those effects like have something evil going on or something like that. Just try to keep it clean like no blood offerings, human sacrifice, total death, etc.
You can have something calm and depressing if you want to put it that way like a dramatic fall scene or something like that too.
Grotesque is, well, I can't say much. Just try to avoid putting that in your ideas. Which means like the above, not a lot of blood, no people being sacrifced, not a whole lot of killing going on.
AS I STRESSED BEFORE NO HENTAI! But if you find it impossible just follow these guidlines:
no hentai pictures of underaged characters
keep it clean(i don't want people thinking i'm a perv just because i put your picture up.)
any kind of orientation is okay(just try to keep it clean like i said above)
For the types of characters, anything is okay. From humans to furries or whatever the heck floats your boat. They can be any age you desire from 5 to 2093579745 for all I care as long as you make it look good.
For Halloween now, like I said before, yes you can put it in even though this is not Halloween oriented. You can also put in anything you want for stuff like the Fall Equnox if that is what you wish but follow the stuff above. I'm sure you can think of something without the stuff i've outlawed or don't want. But I am for the most part leniant with some of the stuff so it should be okay.
That will be all for now. If you have anymore questions, ask me. And if you can offer any help, tell me how you would like to help.
