Lelika, overall it's not bad, but there's too much background, and you need to read up on composition and pay attention to the shape and volume of the highlights on the glass, and pay attention to the light on the objects and the background separately. Try darkening the background, or conversely, making it lighter, making the shadows on the objects longer or shorter, hiding just one object in a small shadow using a cardboard circle as a screen, or maybe highlighting part of the composition with a piece of colored film...
