Wow, looking great that helmet.
Mine is an Anovos Helmet too and if I can make the same improvement suggestions I received here , for basic level , the crl states:
Frown is painted gray and does not leave the teeth area.
This is a esay fix, adding a little gray to the edges and you can use some toothpick and mineral spirit (non acetone) to remove some paint.
For higher levels, (we hope you may want to go further and have the best look to your armor), I would suggest according to the crl:
Correct 'Hovi mic' aerator tips are present. Screens used shall be of a wide type mesh, with the rim of the mic and the inside white or painted white.
Changing the hovi mic mesh is easy, I have done several. look at the following photos and you can try or leave it for a future time.
Cheers.
