You are correct that angle and direction are crucial to obtiaining a natural appearing hairline. Other factors include undulation, clustering,irregular irregularity,density gradient, random hairs and suitable caliber of hairs. Judging from your pictures you seem to be a great candidate for hair replacement. Using proper grafts(my bias is to Follicular Unit Grafting) you should get a superb result and be able to style your hair any way you want.
