The work should blend into your existing density and look pretty natural, however are you on finasteride? If not, I would 100% speak to a doctor about trying it out because you will 100% need another pass on the front to add density if you lose your natural hair there.
On the graft counts, I don't think this is 500 and 100 as some poster said, but I would say there is about 300 max in the crown and maybe 700-1000 on the front. I would defiantly ask for that graft count and possibly even literally count the dots with MSpaint or something to verify.
Good luck! Happy growing!
