I've given my first track for mastering and the plot below is an average from a section of it.
I'm particularly worried about the low frequency terms < 30Hz as they are on average ~ -40dB

I need your advice on this: should I return the track for correction or accept it? Am I being too fussy?
How has your experience been with such level presence in those low frequencies?
Any help/tip would be greatly appreciated.
Warm regards
