I love this song as well but I will be honest it takes a little bit longer for it to keep my attention. It was almost 1:20 seconds in before it actually started doing something differently. I think if you brought percussion or beats in a little bit sooner it would be more energetic. I also think personally that this would sound awesome if it wasn't such a groove sound. I think if it had a little bit more of an up beat club kind of tempo with chunking guitar it would drive the energy level through the roof. But even if you did keep it slow and grooving the way it is, I still think adding some chunking rhythm guitar and just very sporadic places will drive that beat a little bit more. Regardless I really love the stuff that you write man! I wish I had those skills for future songs of ours!
