If it's what you do, don't change it.
Nothing wrong with a quick personal scan before take off and landing - bloody good idea.
Try to do it silently because, if it's non SOP, it may confuse the other crewmember or even interrupt THEIR little 'comfort check'.
I say again: If you have a little personal safety habit you've built up over years of safe flying, don't drop it - that habit may be why you haven't had an incident.
