Frankly, I have more important things to do, rather than urgently try to find references for you.
Maybe there aren't any? ;)
Quick career (till leutenant) in regiment that is considered Neo-nazi even by US House of Representatives - is it not enough?
The only thing you have is a photo of a head that might be him or not....ever heard of fakes?
A true neo-nazi who is such an important member of Azov that he was deemed worthy of a cover pic has surely enough proof of his real mindset, wouldn't you think? There must be alot more to find, his history with Azov for example...statements....his rise in ranks....his training.....comrades who knew him from before and fought with him side by side...etc...
And that would truly clear things up....that photo alone just isn't enough in these faking times, sorry!
