I might put it this way, if I was trying to helpful, rather than... well, like those guys.
Let's assume, to begin with, that the parts are okay. Maybe a bad assumption, but you gotta start somewhere. The other thing that's going to make the pedal work or not is how those parts are connected.
I don't know your impression, but after doing it my whole life, my opinion is that good soldering is not an easy thing; it doesn't just happen. Any acquired skill deserves an investment - you learn and practice. You need to have a solid idea of what a good joint looks like, then how to get there. And it's good to do that as an exercise separate from your project, so you can make mistakes, as many as necessary, without doing harm. Once you have your skills lined up, you just do the project, and it's perfect.
You're kinda beyond that point, I guess. But I would set it aside, learn and practice soldering until I could tell "those" guys how to do it, and then come back to the project. Watch a bunch of videos - some will be better than others. Practice. A lot. Most importantly - evaluate what's wrong, for yourself, and figure out (for yourself) how it went wrong, and what you're going to do to fix it. Practice enough that you can see trends, common problems you're encountering all the time. I just soldered several hundred SMD resistors, progressively smaller, because my SMD skills were marginal. Do 10, evaluate them, improve techniques, do 10 more. And again. It made a huge difference.
I can't see the finer details in your pictures in this tiny phone screen, but I'm going to make a guess that you have some shorts, and/or possibly other connection problems. I see too much solder in various places, and you can suck that up with solder wick or other mechanisms. There are other potential issues.
You're going to have to double check every connection. Not most of them, not the easy ones - all of them. You need to know every connection is right, and none are missing, and *then* you can ask "Okay, so what's wrong?"
