Janusz said it once, Loyd said it twice, I say it three times. Poles and chains. At first, I thought you were talking about foreground clutter, referring to the engine. Given the engine is blocked by the car and engine, you could account that as foreground clutter. BUT, it appears as though the engine is not the main subject, so that may be reason for you not being hit with FC.
If you weren't rejected for FC, why ask if you should have been rejected?
