First one was great! Second one was cool but pretty sloppy imo. Need to focus more on having your hands in sync...you can tell your just sort of tremolo picking and hoping your L and R hands are going at the same rate. At :21 you can see your right hand starts going before your left does if you know what I mean.
Your bends, vibrato, muting, and control on everything else is spot on, and is what made the first one so enjoyable. Just trying to give some friendly advice on the shred part!
