Here is the thing I understand certain people have better Rp skills then others... Therefore you will be judge on these things.
1. Skill- How good your skills are, are you a outstanding Rp'r?
2. Effort- You can be the best Rp'r in the world if you are not trying you are not succeeding.
3. Creativity- The more creative the Rp the more potential you have.
4. Coloring- I don't hate color nor do I like it. If you color your Rp keep it simple and keep the colors equal to your expressions... you will find out what i mean... Also, go with the flow... If you are the only one with coloring you may actually be penalized as it does not fit your opponent's Rp color, therefore it does not match.
There are some more hidden aspects that will be judged. Why keep them hidden? One reason is because, it keeps you from finding weaknesses in the system.
