F-15 Eagle-based fighter

Well, I started this project because I was with nothing to do, but I do not know why, I saw potential in the model and decided to take it seriously.
As the model was the internal render:

Suggestions, constructive criticism and tips are always welcome

Nice start! The model has plenty of potential, IMO the tail rudders are to wide and not aerodynamically friendly and the nose is to angular, other than that great work.

Well, the nose was because I tried to make chines, and I believe that the rendering did not work out. I’m already trying to fix. Regarding the tail rudders, I’ll fix it.
I want to remake the nozzle jet with better detail.
