1) Interesting shapes & textures - needs good light to make the most of that, and preferably an interesting sky behind.
2&3) Both are tilted and lack a sense of there being a subject while cutting across window frames.
4) Photographically the best constructed image - there's a subject, lead lines, interesting textures. Focus seems to be slightly in front of the ceramic dishes (so they're OOF) and the lighting is a bit dull again.
Hope that's useful and not just discouraging. Photography is all about light, and it can be really difficult to get interesting pictures on a dull day.
