It sounds ok like it is, but it might could use just a touch more gain. Be sure to use your neck pickup, and keep the mids up on your amp. You might also try playing with the tone knob on your guitar to help smooth things out if they need it. Try panning the intro hard left, and pan your playback hard right to get a real-time comparison. Also, it sounded like you were playing the exact same thing the whole way through, but the first note of the riff changes for each chord change. You're also playing out of time with the backing :o
