Would this advertisement be creepy?

I own a small business that specializes in home design, and renovation, and I am also an architecture student.

I have been looking to improve my hand drawing skills, mainly by sketching surrounding houses and whatnot. My idea is, what if I just sketched someone’s house very quickly, then attached a business card to it and left it at their front door.

My fiancé thinks this would send the wrong message and come off as creepy, and although I disagree, I can see where she’s coming from. Do you guys think this would come off that way, and if so, how can I do something similar without that happening?
