The hero helmet's base where the ears sit won't allow the ears to sit flat. It's just from the damage and warping the actual helmet has had over the years. That's not a concern.
The reasonable concerns I would have from those images
joe is the warping of the range finger ear cast. Doesn't look too good in mu opinion. Another concern is the amount of fiberglass matting you said there was. It shouldn't be sticking out but I believe it's easily fixable though for the price these shouldn't be concerns.
