I feel insecure of my scar (picture) ?

i had surgery just over 3 weeks ago on my hand and now i have a HUGE scar. i always feel people looking at it and its just an annoying imperfection. i have nice hands and perfect skin, and now this... note: its only 3 weeks after the surgery so my hand is still a bit swollen, red, and discolored from iodine

my dad says since my whole arm is "scarred" anyway (tattooed) this shouldn't matter to me. but i feel otherwise
