Hi Justin and welcome to the site, Mallards are beautiful ducks and often overlooked
because there are so many of them around, the colours in the drakes are magnificent
with a bit of sun on them!
First shot is a little on the soft side, maybe the crop is a little too close?
Second shot is my favourite I like the quirky tilt and the way she is looking
into the lens, the third shot would have been better if you had got down lower or even
if she were looking up into the lens more, your dof seems really short as well…nothing
wrong with that if thats what you are after, but you really need the point of focus to be
in the right place and pin sharp.
Keep on posting it is a great way of learning new tricks :)
