My first critique ^_^ Whats to say that's already been said? It simply looks and feels like you put a lot of thought and time into this. Probably the part that puts an emphasis on "passionate" is the lightning.
I'm not a professional in capturing the mood, but my guess is that the darker colors/ shading is what leads to work having a serious feel. This seems to be a step in the direction that you're trying to work on. I'm definitely looking forward to more great pics like this, man, because this is one of the best in your gallery!
