Hey, I thought this was solid effort overall. I think maybe the vocals could be a bit more in harmony with the instrumentation in the middle part of the song, but I definitely give a lot of credit to the lyrics being inspired by the artwork - I mean, I feel the interpretation of the piece, as it seems aptly titled, "sad" - the sense of this emotion does seem to come through. Furthermore, there is some dynamic and building in the song, and the ending is nicely placed out of the progression of the song. In my opinion, it's not that easy to write a song like this (rock/lyrics), and what's executed overall feels to me like a decent work. Cheers.
