Okay so it is weekend and I had the idea for a art study game. It might be fun as well.
So the idea is that you post a character and the person after you suggest to draw them in a art style of their choice (and leave a character of their own for the person after to pick a style for). Keep in mind that you draw your own characters, the person after you can just suggest art styles.
The art style can be anything, from popular IP's to other artist's art styles and uhhh... even your own (though that comes off a little narcissistic to me). Do keep in mind the skill level of the person you are suggesting styles to. If they aren't as skilled then preferably don't suggest something hard. Also if the art style is from something obscure then do leave a reference (if it is something very popular like dragon ball then there is no need). Finally I encourage you to suggest multiple styles incase the person before you isn't interested in one of them.
The one definitive rule here is it has to be an art style you can do with sketching. It does not have to demand the other to go all out and use colour or a fully inked and coloured drawing. Keep in mind it is supposed to be an art study.
When you receive a suggestion for a art style it is completely up to you whether you want to draw your character in it or at all. It is a art study after all so no pressure to do anything!
Good luck!
Also I'll go first and share some of my characters. The person behind me can suggest art styles.
