Hey Kristoff! Having enough time to spare, I actually had enough time to listen to your entire demo reel! I think the reason some people haven't taken the time to listen is because of the reel's length. It is rather intimidating, haha.
I personally believe that you are going to do fine, based on your pieces. Electronically, you are exactly where I would like to be right now! Aside from a track or two with some threshold issues (like at about 1:31, 7:54), everything else seems to be fairly solid. Though this is merely a snippet of pieces you have made before, I want to say that I was keen on many of them!
So yes - I would say that you are ready for a professional game soundtrack.
