Brick pathways through old castle ruins

A good starting point — with one shift in focus, this scene could really come to life.
Keep doing
You've done a great job creating a sense of scale and distance in this scene. By including elements in the foreground (the paths), mid-ground (the gardens and people), and background (the castle walls), you've given the image a real feeling of depth.
Try next
This wide shot captures the entire environment, but it makes it hard for the viewer's eye to land on one specific subject. Ask yourself, 'What is the main character of this scene?' Is it a specific tower? The flag? An interesting tree? Then, move closer or use your zoom to make that 'character' the clear hero of your photo.
The brick paths create nice shapes, but from this angle they don't guide the eye toward a key point of interest. Try changing your position to use one of those paths as a 'leading line,' starting from a corner and pulling the viewer's gaze deeper into the frame toward your chosen subject.
The large patch of bare earth in the bottom-left corner takes up significant space without adding much visual interest. When composing, always look at your foreground. A step or two forward or a slight tilt down might have replaced it with the more textured brickwork or gardens.
You’ll notice some critiques lean toward strengths to repeat, others toward changes to try. That’s intentional — when a photo is working, the most useful thing is to know what to keep doing; when there’s room to grow, it’s the one change with the biggest impact.
