first off, you've built yourself a very good routine. Good job.
In addition to what you've learned in the beginner's guide, you might want to add some hammer-ons , pull-offs. These are two basic techniques. Once you've practiced these and feel comfortable, take any of the exercises that you were doing previously and try to add hammer-ons and pull-offs. Try the spider exercises with these two techniques :)
The key is to build on what you've learned so far. If you know an exercise in and out, try adding new techniques to it. Mix it up. It's always easier to learn a new techniques while using patterns and exercise you already master.
Good luck, looks like you're doing a fine job with your routine.
