LAck of palm muting is the biggest issue here. OVerall performance is pleasant and sound descent. You keep the timming well and you have a nice precision of hitting strings - not much noise and even tone through all the take. There is a lot of good playing here.
Whole trick in Stephane's lesson is a wide range of dynamics and awesome tone control through all the range - from very subtle notes to those sharp and screaming. It's a fact that original lesson has very soft and not so contrasted palm muting, comparing to the tone of open strings/notes (other words - unmuted ones). But even if it sounds ismilar, there is still a difference to be captured between those. Notice that it's a kind of dialgue - muten question, open answer. Try to attach those details to your take and you'll be even closer to original lesson. Even with those tiny details to fix it is still a descent take. Well done!
