I don't think there are any glaring issues in terms of how the suits fit you aside from possibly tightness in the top block which doesn't really seem to be a problem here. I defer to others like unbel on 3pcs, which I never wear or have thought to learn about (i.e. the vest).
There's a little collar gap in the third and the last one, but I strongly suspect it's how you're posing. I think anything more fine tuned, in terms of feedback, would require more boring poses. But if you are going bespoke (you mentioned B&T), then I suspect they will take care of the fine-tuned things. But on these, they look fine from the pics given the angles. You have flair, and you've picked up pieces that fit well OTR. This is much better than from where I started!
I think one aspect of dressing well is developing an eye for fit, coherence, combinations, etc. Looking at multiple examples, and articulating what is good and bad, is the best way to learn and I think the only way to learn. In this thread, taking part in the conversations is also both enjoyable and edifying.
