Are their any Professional trumpet players or brass players out their i need help with the way my lips are set?

Is it okay for your bottom lip to curve in?Cause my 2nd year of playing my band director told me its curving in and i think its starting to again (i guess summer effects my playing since im not in school no more) and im wondering if its fine if its going in.Will effect my playing later on?Im going to high school and made JV band 2nd band and only 2 freshmen trumpets made the top 2 bands and i dont want it to effect my playing in high school so its im wondering if its okay
