Don't be embarrassed I've seen plenty of pros do much worse. As long as the framing is plumb, square and strong enough to do its job it doesn't need to be pretty because at the end of the day you're going to be covering it with wediboard and tiles (or something similar). No one will see it so you're much better focusing your efforts on making the finished product look good rather than the few bits of timber that hold it all up
Perfecto!
Realised that the top photo was old pipework but obvs couldn't see the bracket in the other one from your first post.
