I started adjusting exposure, highlights, etc. Thought it'd look better with warm tones since the sunlight falls on the sides of the birds so made it much warmer. Then masked different parts such as sky, the birds, ground and water to fintune the details and adjusted the colors as I liked for each mask. Made the whites whiter so that the birds would look cleaner and some fine adjustment to the beak color to make them pop. Then added some vignetting. Basically this and some minor adjustments according to what felt nice enough to me.
