7 months post FUE transplant, should I expect new, thick hair growth? Will smoking affect my results? (photos)

Hi there, I had my FUE hair transplant operation done 7 months ago. My hair have grown but I’m still not too happy with the results as the front hair line is not as thick as I imagined. Do new hair still keep growing after 7 months? Also, will hairline get thicker?I also start smoking around again around the 4th months, can this damage new hair ? Thank you for your help.
