>This has been really frustrating as a junior developer, it's just impossible to get any critical feedback or have someone take a mentorship role.

I've had a situation where I was asking a tall/attractive/charismatic acquaintance for technical advice and he stoped me and said something like "Why are you asking me for advice, you are way more experienced than I am". It's not that I shouldn't have talked with him about the technical matter, just that it was funny that I slid so naturally into the 'underling' role.

segue into something like "Well, I really need another look, another perspective, someone else's eyes on this b/c I think I'm missing something here, and I knew you'd be a good person to ask. I value your input."

And a warning: in your situation you may not know if "you are way more experienced" than he is (he may just be stroking your ego to divert you). I've been in the same situation where time revealed the other guy was hoarding information to his advantage. I talked him into a bit of a reveal.
