I guess this will be a somewhat philosophical post.
There will always be critics... and I, too, am a critic. It's part of the process, and hopefully someone takes a little of this build or a little of that build, and maybe even a little of something I've done, and integrates it into something in the future. It's all an evolution, and everything is a mix or a compromise. In the end, you're the one driving it and you're the one that has to deal with the result... so build what you like. If others like it, or have nice things to say, great. If others raise issues or concerns, often they're valid - think about it and, if you agree, put it into the next project.
I view this truck as just "version two." I actually like what Toyota tried to do with the FJC. I don't think they went far enough (I would have made something much more FJ40-like), but they made compromises. We'd all make different compromises. When I modified the FJC to spend two years in East Africa, I made choices I wouldn't have made for a vehicle staying in the U.S., or a vehicle spending the same period of time in Russia.
If you have a reason for what you do, and you can be honest with yourself (don't "believe your own spin") about what you did right and what you did wrong, you'll get better at what you're doing. I spent years in Porsche denial, watching air-cooled 911's (including the one in my garage) continue to improve. It wasn't until I finally bit the bullet and bought a 997 GT3 that I was willing to admit I'd been wrong and that the newer, water-cooled cars really are better in essentially every way. It's easy to get hung up on what you know, addicted to the familiar. But I'm always up for trying something new, and this project is one of those experiments.
We're all immensely lucky here; we have the time and resources to explore. We can play around with our vehicles, buy some cool gear, go a little further than last year... but it's all exploration (or preparation for it). To me, this truck is a tool, but it's also an opportunity to play around with some aesthetic ideas that have been swimming around in my head for too long for me to not do anything about it. Some will like it, some won't. But the plan has been made... now, all I can do is to execute on the plan as best as I know how.
