WWTLF - Very nice different version in acoustic form. I like it, especially the piano. Just two things, 1, a second acoustic (overdub) comes in and is a little too prominent. Very small issue! 2, there's something in the low end that sounds a bit wool-y. The acoustic and piano crossed a few times, so I was unsure.
Mil.Waltz - Excellent sounding cover. Few ideas to make it shine more. The bass had some mud in it, so a bit of reduction in the lower mids would clear that up well. Good bass playing, btw.
I'd probably add a little more sheen to the backing vocals. The solo guitar comes in a bit high during the middle, but once the "come back..." starts, it begins to settle down nicely. The drums that came in were very boomy sounding. Just need a little taming with some EQ.
Apart from that, a wonderful cover to listen to.
And finally...damn you Dan for getting your WWTLF cover in before me!!
EDIT: Inu's right, WWTLF does cut off on the outro.
