Grumpy teddy

I've finally finished sewing up the teddy I was making for my friend's child.  He looks a little grumpy in the photo... I'm wondering if I should have given him a mouth.  No, trying to sew a mouth on a knitted toy can be a real disaster and often ends up looking like teddy has Bell's Palsy.  That can be emotionally scarring for a child.  And for teddy too, I imagine.
