For those of you that paint walls.....

I have been a busy bee in our hallway painting. The walls were white and the ceiling was green. I got eggshell base and have put 3 coats and when you look at it you see streaks!!! What in the world am I doing wrong? This is not the first time I have painted. I bought a really good roller for this job and it's driving me crazy. Any thoughts?? Of course you only see these spots in the glare of the light so it is really only noticeable when you are walking from my bedroom.... anyway, here is a peak of the color.
