To Add or Not to Add?

12 hours on this art, sat 8 on the original on the left then an additional 4 on the right. I would have another 8 to go... 
My boyfriend isn't really down for more tattoos but I had originally planned on going up on my hip onto my side. Should I leave as is or add to the top of the tattoo?
