This is a pretty nice shot. This would help to increase the focal length even more.
The way to improve this shot is perhaps to lighten the shadows a bit to make it easier to see under the plants (or use more light from the sky). Dark spots in visualizations of parks and pedestrian zones are not entirely welcome.
It would also be good to adjust objects and plants near the camera. Focus more on composition. It is ideal to take a shot with a very rough layout of elements. Then, according to the shot, complete individual models, figures and try out what it will look like in the context of photography. It is good to place very detailed models in front of the camera (for example, plants, these are prepared in Lumion in the highest possible quality). This, in turn, pushes the credibility of the render a little further.
