Masked or unmasked?

I would say unmasked to ensure that people can clearly hear what you are saying. This is incredibly important, especially in tutorial videos. Also, if your channel is new, it might seem awkward to be sitting there in a mask.

Since you mentioned Ghost, Slipknot and Gwar, I think you should try it on with a mask. To match it with the atmosphere, put a little bit of color grading on your videos so it would look dark and aggresive
