out of all the three i would say i like the second one best. the first one the tone wasn't really there. a little muddy. intro was too long, palying the same thing over and over again. there was some clipping here and there. i like the second one cause it sounds like it can be turned into a backing track
a backing track is usually a song compostion whereby people can jam to. say fade to black but with the lead parts taken out. so people can jam without hassle.
i noticed your hand got tired? Some bits were slower than others when playing the same note.
i'll keep listening
edit:
kk you need alot more work. It's just ppwerchords. practise your speed and consistency. keep these recordings and in a cuple of months, listen and see how much you have improved. its a geat feeling
