Really nicely done

Now, you have a really nice one here. If I come to finish my movie or game one day, I'll use that in it !

not bad, but still has plenty room for improvement

this is a work in progress by the sound of it. while it still sounds like the mentos comercial, it lacks the birds chirping (but mabey those would sound crappy with the techno beat.) if you want to add the birds, but still want to stay with the main theme, i'd suggest adding a PVC pipe effect to the chirping, or mixing up the chirp tempo. the begining starts out kinda slow, and all of the audio channels should start in alot sooner and shouldn't wait as long for each one to start in. also add in some more bass.
