This girl wrote "pretty impressive" on my facebook profile pic...should i?

This girl wrote "pretty impressive" on my facebook profile pic. Can I comment back something like..."it be pretty impressive, but u are impressive and pretty..lol" I just want to say it because it's "somewhat" clever play on her words. I don't want to come off as though I give out sappy compliments to every average girl....kinda lame in my opinion... i just think it's something clever to say...do you think it would be alright??
