Painting upstairs

I had a huge priming and painting party about a month ago. We primed my whole upstairs on the Saturday and put on the color the next day. I had at least 8 people to help me each day and I want to give a HUGE thanks to my friends who came out.

I've been gradually working on touch-ups. I needed to reassess the wall I decided needed to be teal. I absolutely love the color, but dark paint shows flaws easier. I ended up getting satin finish, which also shows the flaws b/c it picks up more light. Of course the wall that I painted teal was the most flawed wall in my room. I sanded it again and it has helped some, but that wall will remain flawed unless I mud the whole thing since there were so many patch jobs already done on it.
I repainted the wall and the satin finish still shows the flaws too much. Tip: Keep in mind how flawed the wall is when picking out your paint finish and color. Another tip: I primed everything white, but if I could go back I would have bought tinted primer for that wall since it needed the most repairs.
I'm going to do a light sand over the whole wall to remove the satin sheen, clean up the dust, and repaint the whole wall with a matte finish. That should help some.

I still need to do touch-ups with the other colors and repaint areas of the ceiling that got paint on them. I should have bought stock in 3M painter's tapes. Once I finish the teal, I'll need to tape the border so that I can finish painting with the tan color on the other walls. I'll also need to tape off the ceiling so that I can paint all the way to the crevice. That meticulousness will pay off in the long run, even though it's time consuming now. At least I tell myself that while my room is in disarray :)
