Darwin looks absolutely PRECIOUS!! Relax...his hair will grow back just fine, perhaps even better, a good trim never hurts, hehe. My girlie is 9mos and from the beginning, I decided to groom her myself. I'm not fond of the treatment from groomers, like an assembly line or something. Believe me, learning to do it is by trial and error for me, but getting better at it. It will grow out really fast, you will be so surprised.
