Hey there!
Most of your take is really descent. There are just a few moments towards the end where you tend to get a little out of sync between hands and timming goes a bit off. Aside from this I have no additional complains. Well done
As for the picking strength - that's a good idea to practice hard picking. The more gain you give from your hands the less you'll need to set on your amp. This will profit in less feedback and less hum or noise from the amp. You can also adjust the width of right hand motion. For slower picking, wider motion helps to keep better timming
