I personally would send it. My baby's head only came up halfway on the photo and the check and send at the Westminster Bridge Road
PO told me it would not be accepted. I sent it anyway 'at my own risk'' and received the passport only a few days later (albeit with a terrible photo).
In any case, unless you are in a rush, if the application isn't accepted in the first instance the passport office will ask for additional photos.
