Here are a few comments, the two dotted lines appear not to be parallel, I presume they are meant to be although the real aircraft does taper a bit in the opposite direction but no one will notice.
The rear of the engine covers just before the exhaust outlets curve differently to the real thing, my drawing attached is a bit more like them.
I assume there needs to be a notch in the top fuselage plate to receive the fuselage nose piece.
Just for interest here is the underside of the HMM F15 slope soarer that I carved the moulds for, way back when. The F-15 is a complicated but beautiful aircraft (the real thing I mean).
Hope it helps.
Roger asks: wow, that's a big one! Where does the Jetex motor go?
Rob Smith and I have been refining the plan ready for publication. Below is a 'low res' copy for your comments. If anyone would like to build an F-15 from the draft plan, correcting if necessary during construction please tell me and I'll send you a printed copy.
The coloured templates will also need some refining.
