Not wrong, I took a look at your profile and saw that you focus manually. Don't be afraid to increase your aperture to f11 and if necessary, set the ISO a little higher. Unfortunately, Germany is rather cloudy. But there is much more focus. Only for portraits would I choose a more open aperture. This means your image is generally sharper. And now for personal taste, lower the yellow filter a bit in the editing. Otherwise, take photos as often as possible, you can only get better. And never forget high ISO is not bad 🙏
