Denise,
Beautiful low angle shot with nice detail. There appears to be a slight magenta cast on my monitor although that may be due to the light at daybreak.
Love the low angle, great morning light with a beautiful catch light. As you mentioned, I would go for a tighter crop (top and left). I see some tiny noise on the BG ..but maybe it's just me...love it...
I would crop just a bit from the top Deniss but I like the compositions with lots of room at one of the sides. The shooting angle and preening action is just fantastic and love the nice light. Oystercatchers are really skittish in the south of Spain and I am so envious... :-)
