Gimmicks are a blessing and a curse, IMO. It gives you an identity but it also limits what you can do without breaking the rules you've set with the character.

With the blank slate you have, you can pretty much do whatever you want with Travis and it will make sense.

All that really will matter is how well it is written and how well you outdo your opponents. Like I said before, the length will only matter when you're up against someone who is producing the same quality of work as you are - obviously the guy with MORE quality work will win every time.

People are almost always willing to agree on limits here though.
