My sound mod

I´ve been working on an update for my mod, which I will release after the December Update. Here´s a little sample. Any opinions, thoughts, suggestions?
My update includes bsp´s which means I have two vpk´s. From what I heard, The December Update includes a new workshop-tool that allows merging multiple vpk´s into one mod. When publishing this, does workshop just replace old content with new ones?

Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
