In the first image, focus seems to be the primary issue since too much of the bird is out of focus. Eyes and chin area are also underexposed and there are some artifacts in the sky.
The second image is quite underexposed. A few quick edits in Lightroom will allow you to get this image accepted.
Apart from what Jlll...C said, the horizon of the landscape is slightly tilted to the right
Auch wenn es aufgehllt wird, sieht man im Landschaftsbild keine Details, die Bäume bestehen aus "Pixelklumpen".
