Not really angry...
This song has a decent Glitch/DnB feel to it, which is cool and pretty original, as far as NG goes. I personally dislike how much you panned each individual instrument, but some people might enjoy having their sounds that left/right side biased. From 0:20-0:52 the left ear experiences a noticeably greater amount of sound, and generally a lack of balance for that long doesn't do too well.
Also, the song ends really abruptly. If you wanted to make this seem more like anger in the traditional human sense, you could add a ten to twenty second fade-out section where the anger "cools off". Abrupt endings, especially when it seems like it's mid-measure kinda lacks professionalism.
Hope that helped (check out my stuff sometime),
