I need orthodontist tips

Okay thing is i have an appointment coming soon to try check for braces if it suits my problem (im 21 so idk if helps) and honestly I think my issue with my side profile is not that alone. I need someone to rate it and give tips on how to make it better so i know what to say coz i really have no idea how to analyze to see whats wrong other than my obvious bimaxillary protrusion probably. If anyone can help please let me know and Ill give my dc prob in DMs (Ill prob DM later on coz i wanna sleep now)
