Yep...I agree with Ed. It seems that the main mistake you made , are the exhaust pipes. I'm not sure but these parts should have been attached inside of both of the fuselage halves. These in your image are sticking out a little bit strange.
I have the same model in the "waiting to be done" line. Your model looks just fine to me. I must admit that i like more "used" look of aircraft's from WWII but also like to see clean and precise work. Did you had any problem in decal applying process, as they are quite big for the size of the model and covering quite large area of the nose?
At the end, good work.
