Hi everyone! its so cool to have all these files available to practice , i've been serching something like this site for several years , its realy realy great this site!
the comments i made to this chap(?) is also very applicable here too, interestingly.
i recommend you check your mixes in mono, as this flags up problems especially in the low-mids. panning frequency masking issues to opposite sides loses you power in the delivery.
