Building realistic jets in LEGO can be quite a challenge and this is a pretty good effort.
I saw this on flickr a while ago and made a few comments then. Having taken a look at it again, I have a few more.
As you know, I tend to build my jets a bit larger and don't use minifigs with them. For minifigs this somewhat smaller model is probably better. The proportions aren't perfect, though. A quick count tells me the model is about 50 studs long. My own Eagle models
, are about 70 studs long. Even though your model is a lot shorter, the width of the forward fuselage and the width of the intakes are the same on yours as on mine. IMO that makes the forward fuselage look too big relative to the rest of the aircraft. Those folding intakes are nice, but I had sufficient space for them on my models. I'm not sure you do too.
You don't show pictures of the bottom of the aircraft. I'm not sure why, but I suspect the relatively large width of the jet near the intakes compared to the width near the exhausts gave you some issues. I'm very curious to see how you've fixed those.
The dark grey/bley suggests you were building a Strike Eagle. One of the other things that makes this version stand out compared to regular fighter Eagles is that they typically carry a lot of bombs. Your model would look more convincing if it too carried a full weapons load, as a few other posters have already mentioned.
The canopy is almost always an issue when building jet fighters, since the available pieces rarely match the shape of the real fighter canopy. I agree that it isn't ideal for them to be overlapping, but this is probably the best purist solution you can come up with for an F-15.
