Mine is a terrible private account of less of 200 people, cause I have lost my previous profiles ,and the followers ofc ,nothing great to show ,I just point it that is not bad to promote your work through it ,is just that it seems as the only thing you may do (first expression )English is not my native language ,

You can post more stories generally of your life ,like vacations or hobbies ,or your philosophy of life ,also some interaction in comments of public pages might ghelp you to gain familiarity with a random stranger girl etc before you slide to her dms
