Yes I think this design overall will be fine. Without seeing all sides of it it’s hard to know for sure. I might make sure on the left it has an ear cap and add key slots in the back to make sure it has some of the hallmark Mandalorian elements to it. For the spiked parts of the visor I’m not sure how this would work with the top curved part of the cheek. Painting it on there might be easier here but that is up to you. Another option might be to move the spikes back off the cheek but in front of the ear cap. NME did a nice job of incorporating a spike at the back of the visor going down in their Assassin bucket.
