I like it but it lacks brightness in the face, I can only just make that the bird is looking towards the camera and its not the back of its head I'm looking at
Not bad for just getting started. Carolina Chickadees are notoriously difficult to photograph. First, because they are small & quick, and hardly ever sit in one place for more than half a second....And second, because the black eyes are set in black feathers.
You need to brighten your exposure a bit, almost to the point of over-exposing the belly in order to bring out the detail in the face. And, as with most wildlife....especially birds, always remember the catchlight in the eye(s).
Just a bit of PP in CaptureNX... cleaned up the bird a bit, lightened the face and neck with a control point, cleaned out the noise painting with blur, and popped up the brightness and saturation of the green a bit... and a touch of sharpening... total time on task 4 minutes.
I think it helps a bit... although I am editing an extremely small JPEG so the quality deteriorates rapidly due to the file limitations. It is amazing what just the smallest smudge of PP can do to an image.
