Very impressive
The TIE bomber is very nice, although I am unsure about the curved bricks used at the back. I haven't seen the movie in a while, so those may be accurate.
The TIE advanced is also extremely cool. You used 4 1x1 cheese slopes in the back, I think the engines are in there somewhere.
The TIE interceptor is my favorite TIE variant, and you have done an amazing job. The way the wing are done is simply genius, I would have just used wedge plates and left it at that, nice work.
Overall, you have made 3 incredible looking vehicles from star wars. If I had one critique it would be that maybe you could have tiled over the wings? That probably would have made them more expensive though.
Have you thought of making a TIE shuttle? A youtuber by the name of ec henry made a computer model of it.
