You look just fine, bud! I see nothing strange about your noggin at all. Heads come in all different shapes and sizes. With so many possible variations, there's no such thing as a "right or "wrong" shaped head.
If anything, the negative types are just jealous of the guts it takes to shave off a head full of hair. The opinions of such superficial people shouldn't matter to you, anyway.
Don't feel bad, my friend. Be proud!
It looks fine to me too! It's funny how 2 dimentional views, such as pictures, can slightly change the way something 3 dimentional looks, like a head. The same holds true with mirrors. When I look at a mirror, I see things that nobody else sees about me, partly because of the exact angle that my eyes are looking at me.

I say, go out and live lavita loca!

Go crazy!

You look great!

Life is too precious and short to worry about the small stuff, and it's all small stuff
