Hello new person. Interesting entry! I did not expect it to kick up like that.
Battle of the Holly Cover
Epic sounding. I really like how it feels at 0:43. There is something I want to say about it, but I don't have the musical vocabulary to properly explain it. It feels like the notes are too 'short'. Like everything is in a hurry to end, they're just being struck and released quick. It gives the song a sort of airy roomy feel, which feels odd to me. From the strings or horns I can kind of see this, but when the organs do it they feel somewhat empty sounding instead of a solid heavier component. That is the best I can explain it.

I was actually expecting the lead to come out a little heavier, but by no means bad. Maybe a little tweak to the mixing could fix that feeling but I couldn't qualify to say how to go about that. The softer introduction was a nice touch.
