why does my paint look so bad. this is after two coats of primer. I used this exact same base in every other room of my house and after two coats had perfect streak free walls.

I decided to color drench my den and it currently looks like this. guys I'm scared what do I do. ;'( just bought a second gallon from Lowe's. the ceilings are 9.5 ft. I can't do this bro
