I am fine with the composition...it gives a feeling as though the birds are taking centre stage! The pose looks good too. A bit more sharpness will be good...if you haven't been adding sharpness to your images and are posting straight out of camera, it is important that you tweak the white balance/brightness/contrast/saturation/sharpness/ levels/curves or even all sometimes because we can't expect the camera-lens to deliver the exact desired result every time
