Nobody's said anything so here are my brief thoughts:
1) The colours are very nice, and there's a sharp delineation for most of the person on the left. Sihouettes are about shapes, and unfortunately the shapes on the right are muddled. If one could distinguish between the mother, father and baby more clearly you might have something interesting. The child on the left is sprouting a second head. Also, these are clearly the backs of heads... so they must be looking at something interesting. Is there any way that could be incorporated in the frame?
2. I really love the colors here. However, a low shutter speed has created motion blur. Also, getting birds in flight with a recognizably birdlike shape is a bit of a matter of luck, or using bursts on the shutter. In this case, the bird on the bottom is, to me, more birdlike than the upper one.
