45 days after FUE: Would you please let me know if this density and redness normal? (Photos)

Hi everyone, I had my FUE of 4700 grafts in Istanbul 45 days ago, pictures attached for first day, 15 days,21 days and 45 days post operation. I have now mixed new hair and transplanted hair, however, density is quite low, besides, from time to time, I develop some redness that transforms to acne like things that produce a white secretion similar to pus, I treat that with local antibiotic and disappears after 2-3 days. Would you please let me know if this density and redness normal? Thanks a lot
