From what I can tell your hair looks alright at it's current state, I can only assume that's a NW2 but it looks good because of your long face and not massive forehead..
I'd say don't do it, because honestly buddy you look good. I would not say you would look good buzzed, you seem to have fairly thick hair? Or am I mistaken?
Because you should really take advantage of that. You'll loose it soon buddy, who knows maybe a year from now? 10 years? Or more?
If you really hate how you look then so be it, but I wouldn't!
Style your hair, take care of it.
