Telling you when to practice I can't do. You know when you have free time. You said you have maybe 2hrs a day to practice right? Lets try breaking it down like this and see how it works.
15 - 20 minutes on lesson 1. I choose Kris's lesson because it is similar to what you where wanting to play in your video. I want you to listen to what he is telling you about technique and muting with the palm of your right hand. Then apply this when you play your power chords.
30 minutes on lesson 2. Smoke on the water is a classic, which all beginners should learn to play. Plus you will learn a new way of playing chords.
30 - 45 minutes on lesson 3. Muris's lesson will help you get control of your left hand fingering and teach you how to start picking. Play attention to how you hold the pick and your posture while playing. Don't try and practice sitting the same way you did in your video. This will make thing more difficult and create bad habits as far as technique goes.
I would like a minimum of 1 upload a week. More is better especially if your having problem. I'm here to help so don't be afraid to use me. You can't ask to many questions.
Does this plain sound like it will work with your day?
