The biggest pieces of advice I can give are:

1) if you are gonna base your character off of real life styles, have some rudimentary understanding of it. I have little to no boxing skill.  Tre'Yan should have adopted a switch hitter stance. 

2) Find your weaknesses and work on them, don't go for the first defense that seems logical, look for all avenues to take. That's a problem I have, and its probably what keeps me from being better.
