That is part of the pixel editing - it definitely goes below the Levels layers. You're doing everything just right.

Good.

I don't understand the point of your distortion in this one? It seemed fine to me as it was. If you're not going to correct the verticals (and I don't think it's necessary) I don't see any reason to fiddle at all?

Good.

Sorry, what's supposed to come after Levels? This looks excellent.

Great work.

Hey, good!

Great.

Yeah, that's better. Where the blue wall meets the carpet isn't horizontal.

No, I think you've made it worse. Leave this one as is.

Great.

Yes.

Yes, Distort is the one. Perspective to begin with, then Distort to fine-tune.

No, I mean actually stretch it vertically.

Honestly, yes, I'd use a solid colour layer, then a D&B layer clipped to it to add a bit of shape.

What about the poster at the right?

Too narrow, yes? Needs to be extended horizontally?

Should the bottom right corner point be dragged downwards a bit? Where the wall meets the carpet doesn't look horizontal.

Is it a bit wide? Do you need to extend it vertically?

Yeah, I reckon.

Yep!

It'll be transparent once you turn off the Background layer

There just isn't enough brick to work with, is there?

Yes, that's right, perspective correction must always be done on a duplicate layer. https://www.damiensymonds.net/2014/03/distortion-or-perspective-correction.html

Although not quite perfect, easily good enough to use. Go for it.
