I can't see anything wrong with the shape of your head.
I went through the same anxiety a while ago and it was only when I said "f%^k this $hit!" and never cared about what anybody else (wife included) thought about my new look, that I started to accept my new look and started to walk tall.
I had doubtful days and had days where I decided to let my hair stubble grow a little but I soon returned to shaving it back off.
The root cause of my anxiety was down to my thinning hair and what I should do with it. In time I have learn't to get rid of the hair and accept things for how they are. Life is too short to worry about what anybody else thinks.
Strangely enough, no one has ever said that my hair/head looks bad. I've had a few comments saying that "it suits you" but no one has or has had the balls to say it looks terrible. I do get a few looks if im out and about but I am 6'4 and secretly think i'm Jason Statham, so will give ANYONE the look of death, but hey ho, that's life.
