I did these head shoots for personal use and people are telling me go and share with agency/ help me to find an agency because I really don't know

I am 29 Iranian born and raised I actually did these photos to choice one of them to my Instagram DP and that's it, but people say go and share them with agency 😅 the problem is I don't have or know agency I am beginner at the same time I feel like no I am just 175 and it's impossible to take me or maybe I don't have the model potential etc.. I am here due to people requested me to do this.

Do u think these photos look good to share with agency? What photo u like the most thank u because I might add on my DP😘BTW I might do more head shoots today with different outfit. I need ur opinion 😭
