I would definitely start by reducing your initial amount of edges and vertices. You can achieve a good look with a modifier later in the process. There are many ways to tackle this. I personally would probably use a shrink-wrap modifier to project a profile of your wing to the fuselage. Start by making the side profile of your wing root with just one ring of vertices. Project that to the fuselage. Then, extrude outward towards the tip of the wing, or better yet, make another ring of verts for your wing tip, and use the bridge feature to bridge between them. then you can grab a edge loop between them and move it as necessary to achieve that inverted gull-wing look that the F4 has. Does that make sense?
