Good for you buddy. Kudos to you for having the courage to try something new. You look great! When your hair is thinning - the shorter the better - it "fools the eye"!
I might suggest that you take the sides up even higher and tighter; that way the bald spot on the back of your head would not have so much of an "outline" under it.
Whatever hairstyle you choose, or even if you choose to fully shave your head, what matters is how it makes you FEEL. If you feel good about yourself you will wear your hair/no hair with confidence. People pick up on the way you feel by the way you carry yourself and they will respond positively to you!
Once again; congrats on having the courage to change and to embrace change!
