Yours looks way better than mine. You said that you learned what not to do. What was that? Curious because I fiddled with mine a lot longer than I probably should have.

I decided to double the thickness on mine, and wasn't too worried about the alignment since it was under another plastic. It is held in place on the bottom layer (hard to see in the photo). And it's not like my PH is a showpiece or anything.
