I love this shot! I might have chosen "New Scent" or "New Scents" or "Two New Scents" as a title - I tend to think of odor/odour as a less-than-pleasant smell. Just my initaial thoughts. (The photo RULES, by the way!)
This is a great photo and you did a really nice job with the duotone. My only suggestion would be to crop out the fenceline at the top since it draws attention away from your excellent subjects.
I think this is a great photo and really like the choice of B&W. I think the composition is very good also, but I wonder, is there a reason that you didn't leave the fence and trash out of the frame.
I wonder how much all that wool on the mama weighs?
I wish you had cropped this tighter to concentrate on the sheep and lambs. The distracting fence and trash in the background could be so easily removed. Definitely works in black and white - quite a cute photo.
