To me it sounds like Heimdallr says his own name like Him-Dallir and to me that is super weird cause I thought his name was "HaimDahl" (like how you say hello / Hi! followed by an M) . Or if the R really needs to be there HaimDallar sounds better to me.

Nothing serious but if you make some skin in future maybe he can say HaimDahl or smth instead on pick screen.
