I dont have a problem with the black head, I would try a bit less tail though. I have been studying jig color combos for over a year and one theme that carries thru in a lot of jig patterns is match tail color to head color so for your combo above a yellow or brown or white with brown specs head may be more apealling.

I tie a BG jig similar to yours except I use an olive head with chartreuse/black eyes. Pearl crystal chenille body and natural squirrel tail tail

BTW put a white/black or silver/black eye on that head and it may change your thought completely
