It looks like either the lines with the black part on the front of the cockpit and nose didn't line up, or maybe if shifted during assembly. It is kind of odd that models with simple fuselages, in that sense of a straight tube with a point, are most sensitive to any kind of accrued error. If you would have show in in just the 3/4 views, it would have never shown up! Just make a gentle camber and form the wings into a wing foil, balance it out and throw that sucker reall hard, it will fly just like a Dart. I used to make F-104's at Sikorsky's and we would throw them at each other. Sometimes, we would launch them with the compressed air guns. Under 100 lbs of pressure, they flew really fast. I balanced one out really nice with one of those tiny ESTES rocket motors and that thing flew amazing, it did this incredible arc around 60 feet in radius, then, because i used the wrong type of engine, the nose blew off and the crash was spectacular. A Paper plane , on fire, on the ground. It looked like a real crash scene, except no one got hurt. Nice job. Really. Most people would have posted just the views that didn't show errors. You actually could cut that nose off and fix it, it wouldn't be hard. Just draw some kind of graphic to make it look aligned.
