Welcome to the forum! I like your bike. The Peugeot lion on the fork is a nice touch. The only thing I see that needs to be done is to put that shifter cable in the right groove, and that's an easy task. Once you've done that I'd just clean it, give it a wax and ride away. I'm fond of CLB brakes, and they're French so they match the bike regardless of their originality. Now, if it were mine, I think I'd lose the reflectors, change up the bar tape and saddle and go for something like this:
But that's aesthetics, not function. Have fun riding your new bike!
