2. About the pictures with fire:
You can clearly see that he looks confident, maybe even defiant, in the first one on the left, he looks directly at the camera, but fire, as you said, is dangerous, and as the fire on the match gets closer to his face, to his mouth, the most important part of his all body (don't forget, he's a singer, without a voice and a functioning mouth, he looses his "purpose" in the band (cue to padam "če mi nič ne uspe, če izgubil bom vse, kar sem si želel"-"If I don't succeed at anything, if I lose everything I ever wanted")), his eyes go down to check the fire, what it is doing and where it goes. On the third picture, he raised his head as to take distance from the fire, he's uncomfortable because the fire got closer, it's incredibly hot. And he also changed how he was holding the match, he's almost trying to let it go maybe because he's scared he will get burnt from it.
