I haven't even commented on your last somein30 set. You put some much work into that. I at least wanted to look at the pdf before commenting. Well, it's bookmarked and now I'm commenting here first. I mainly know Steampunk as something more of a visual genre, so it's interesting that there is also accompanying music. However, the icons do fit very well to this idea of Steampunk I have in my head :D
The brass colors are awesome and I love all the intricate compositions. The rich shadows and deep reds of the Dark Cabaret icons are stunning. I love how the gritty textures pull the two styles perfectly together! Finally, I also love the Supernatural and Avengers icons. There are so many little details in these icons <3
