I'm an artist. Im not as good as Podukan, but then again.. no one is better than him.. god he must have so many women. Anyway, I'm going to teach you how to create a character.
First thing to do is choose an animal (that includes humans) dont choose a shape dude.. there are too many circle shaped main characters already.. . So for this example we will choose the BEST animal, the DOG.
Then you have to choose the color, you've got brown.. white..or black.. BUT who sais we cant choose BLUE??
So blue it is. I recomend you always choose colors like Blue, green or RED. Then you have to think on the accesoriesl.. like hat and stuff.. so give the guy a shirt of the color you want.. a hat.. and big shoes and gloves! all diferent colors! And you've got to give him black spots on its skin.. so give him a spot on TOP of his eye, that is really cute when a dog has an eye surrounded by a black spot.
So in conclusion there is no better way to create a character than follow this method. You should ALWAYS do this, otherwise your game will fail to be fun, this is like basic stuff.. so you should always do as I say.

Go ahead.. create a character and post it on the comments area, I'm counting on you! (use your imagination)
