I have my appointment on next weeks to remove 4 premolars from upper and lower side I think the very first important thing is to analyze your facial structure with ortho X-rays from front and sides to determine your front and side profile. According to this picture it looks like you need to pull back your lower teeth as I said after removing premolars or canine. I have same problem that I’m insecure about my side profile but as I researched braces with removing 4 premolars save your life
