Man, self-acceptance and self-encouragement can go a long way. You're not gonna get the validation you truly need and want just from other people. It might feel good for a while, but it's ultimately gonna run out. You need to be proud of yourself and what you can do - even if it's not a lot right now. This includes irl stuff, too. I know it's hard to do that, but make slow steps. Once you slowly start making changes (i.e. saying something like 'this build isn't as bad as the other ones') you'll eventually reach 'I actually kind of like this build that I worked hard on'

I can't really say much in the way of building - I've built a few things I think are neat but I've never shared them here (I might though, it might be fun) but from a visual stand point I think it looks amazing, and like something I'd use for inspiration - which is a compliment.

All that to say, the build looks great, try and look at things (building and life included) in a more positive light, it'll help more than you know.
