What a wonderful series. You capitalised on being in the right place and the right time. I like the first shot here as it shows the interaction between mare and foal. Perhaps I would crop a little of the foreground and of course, if it had been possible to have had the foal facing you it would have been perfect.
I do like the background grasses with their bit of colour.
You are very fortunate to witness a birth, and thanks for sharing the moment. Excellent exposure on the mom, and just love those wobbly legs of the foal. Well captured Marc.
