I agree with Royal that the colours are the first thing to strike me on opening up the photo (the red is too saturated). That and a visible dust spot a few centimetres above the flightdeck.
I think if it was just the tunnel then maybe it would be okay, but it is all the other distracting 'stuff' there too which causes the trouble for you I think - that 'tube' on the left, and then the obtrusive signs and fencing. That, together with the construction equipment behind the aircraft, is plenty to get the motive rejection, I am afraid.
All the best.
