X-Wing modelling

So on to my final model, the x-wing. I wanted to really put my skills to the test with this one. The first little trick I used was on the nose cone. The picture has a small wedge cut out of the front. Rather than boolean this, I wanted to try it with extruding and target welds. First I used the connect tool to form the rectangle. Because the nose cone was sloped, but the wedge was flat, just extruding wouldnt do this. I extruded inwards, then deleted the surrounding polys. Using target weld I then rejoined the vertices like so. Afterwards I used the create poly tool to fill in the gaps.
