The two that really stood out for me were the AIC cover and Reason.
On Reason, I would maybe cut down on the tremolo picking-heavy solo towards the beginning. For me it just takes away from the beauty of the acoustic and flute intro. If you wanna do it, put a heavy riff in its place and try playing the solo on top of it but an octave lower. For me, however, it's just distracting and it unnecessarily takes the song in a direction it shouldn't go, mainly because you go right back to the original riff right after it. It almost sounds like you spliced a solo in there from another song and just randomly put it somewhere. If you're going to keep it, try using the neck pickup on it...it would be much warmer and more fluid sounding and would cut down on pick noise. Just my opinion, though. It has the makings of a really cool song, but I think that intro solo needs to be reworked without so many hammer-ons and pulloffs...put some more melody in it. Dig the vox. Great job, Myke.
On BGWTB, the lead guitar again I think needs to use the neck pickup...the solo's much too cold. If you're already using the neck pickup, dial down the highs, give it some more mids, and boost the lows a bit...lower the presence a bit too. It's also out of sync with the acoustic guitar. The bends need to start on the strum, not before or after it. Also the bending needs to be a bit more precise. As far as the vox, although they were in tune, I was sadly completely unimpressed. It's flat and droning as well as out of time with the music. I understand Dan was trying to kinda put his own flavor into it, but it's not working. I think it needs to be more in line with the original, not in order to copy it but because it's sung in that cadence for a reason. I think the words need to be enunciated a bit more strongly (not harshly) and with much more inflection because they're kinda soulless like they are now. They also need some reverb and a bit of delay.
