/ic/ - Artwork/Critique

Complete and utter beginner and looking for instructions after reading the sticky.
I tried reading drawing from the right side of the brain and i simply couldn't get into it. I was also looking into keys to drawing and The Art and Science of Drawing. Should i stick to those two and then try DftRS or just stick to any particular book?
I was also wondering if Draw a Box could be good for improving my line quality since i really like felt tip pens and want to work with mostly inks, I've read people who only do that shit end up never improving so is there a recommended balance between both?
