Hey there again!
You have a great attitude and you respecfully attempt to the lessons.
I'm sorry to say this but it surely will nto surprise you. This lesson won't teach you much - it's wa below the level you are able to reach with relaxed playing. To be honest I have nothing to complain here. Every note is even in tempo and even in attack which I like when we speak of slow alternate picking.
My personal opinion is that the actuall progress starts from the point you start to experience problems - slow enough to focus on what you want to hear but fast enough to start bringing some fingers twists etc.
The saying that you need to play slow to be able to play fast is more complex than these few words and in practise need some exlpanation. You always need to know (besides the moments of inspiration while improvisation is in progress) exactly where is a place of each note and what is the picking direction assigned to it but....hands mechanics change while the tempo increases. You need to practise at the tempo where you start to feel discomfort and you need to apply changes to your hand resting point ,angles, pick grip etc. You will see it works different becasue every mechanism needs some improvements to get more efficienty instead of just "overheating"
I'm afraid you hand "layout" will lead you to a stiff forearm and that's whre most of strength and speed will come. In theory ...Jon Petrucci does this and it seems to work fine for him...but...unless your really want to look like John, Zakk or...Hulk Hogan...(
) there are wasy to achive good speed with less physical effort. To do so you need to involve more muscles of your hand - besides forearm, there should be wrist rotation and thumb motion.Thenit's more related to Malmsteens technique.
You current layout is more jazzy I would say...with fulyl stiff palm. I've been where you are now and I remember how I had to completely redo my hand mechanics to be able to skip to a different level. Maybe it's time to apply little changes one by one so it won't be too much at once. Just loudly thinking...
