Sure.... since each character in this font/logo is custom (it'll require a redraw to change it) it'd help to have a little more input and understanding of your preferences.
Do you have a favorite font? Do you prefer SanSerif? Script?
I assume this is for signage -- distance legibility important?
I am happy to make the changes... a little more input would help me go in the right direction. You can comment on fonts in general or other fonts used in the contest.
