i dont know what is misssing.. i'd say the birds are flying to the wrong way.. meaning if they sould fly to right, under the pov of the composition would be better . only that..
and maybe a thin frame, simple or just a black bg..
but let me say this is great image.. light and tones.. and special mood are here..
Thanks Silvia for your assessment.
Seabirds around here spend far more time flying into the wind, for the same purpose as an aircraft landing or taking off, they get more natural aerodynamic lift. In this particular picture, the gulls were flying past intermittently all evening to the night-time nesting ground to the left. Being a romantic, I also like the idea of them flying into the sunset I guess .
But I Wish I could have got one or two birds a little closer to the camera maybe.
Silvia, you are correct about the need for the birds to be bigger. Thanks for your suggestion. They would then become the "subject" around which the whole picture revolves. At present to me, the picture has very nice scenery/background, but nothing to "focus" on. Cheers.
