The pattern is good, I think the tilt does add to the photograph but it is lacking something ... I'm not quite sure what though! If I work it out I'll let you know!
Even on the vertical/horizontal I wouldn't be able to figure out what this was. The choice here adds a graphic design feel that is appealing, but I still feel cheated not knowing what this was...tiles, a building, wall paper.
I see a ton of what appears to be compression artifacts in this. Visible at all the high contrast edges. You file size is good, so I think this must have been highly compressed during editing, before it's final save. A good thing to do is if you need to save your work, save it either as a TIF, which has no compression, or in your editors native file format.
What is it? It could be a building, but it seems smaller than that. I think it may be a tray to hold microchips.
