Well done mate... You are on the path to seeing if she likes you or not.
As was said above, you dont want to change so someone likes you, in the end no matter how you change, if she wasnt interested in you to begin with, she will most likely not even noticed you changed.
The advise about making a move soon so you dont become "that creepy guy" was very wisely given.
*MaJiK*
There are not many things I fear in life, but disappointing you is my greatest.
I love you even with your flaws... I love you because of your flaws.
