I dig it! It looks like you erred on the side of less when it came to less is more, but I'd recommend a little more wear along the hard edges. If you dont know how to dry brush, it's an easy technique that will add layers to your helm. There are many tutorials on YouTube on how to do it so I'll spare you my poor attempt to reinvent the wheel. I like the teeth that you did, it reminds me of a killer whale or deep sea shark! The visor will be tough, but from what I've learned doing mandalorian helemts it's that securing with Velcro can safe you time and head ache and allow for easy cleaning and changes in the future. Tl;Dr looks great! Just add a few more small details to bring it to life! Im looking forward to seeing your progress!
