I'm sure there are online communities that would provide what you're looking for. I've been a member of cboard.cprogramming.com for over a decade and that community is exactly like what you're looking for. It's focussed on C/C++, but people who post their code either with specific questions or asking for general feedback will get a wealth of advice on how to avoid common pitfalls, how to do things better, and how to be more standards-compliant. For other languages, ask around for the good communities - they must be out there.
