I stopped rewriting a guy's logo 11 times when he said 'make it pop' and finally just sent him the file | Client Nightmares - Freelance Forum - The Community for Independent Professionals
And honestly "make it pop" is usually code for "I don't know what I want but I'll know it when I see it," which means you could send 50 versions and none of them would be it. The real move is to stop guessing and make him pick a direction, like ask if he wants bolder colors or just a cleaner layout. Half the time they say the words and don't even know what they mean themselves. You did the right thing by just shipping the file instead of burning another week on it.
