Hello Sim!
Here is my criticism, I hope it is constructive and helpful.
1. The need to register at soundcloud is not very convenient. An option to send a submission to you would be good (I did not find it mentioned in the letter).
2. I would say that the sample is not very inspiring, at least to me. I would think that the point of offering a sample is that it sounds unique and interesting. That kind of noise I can easily generate in two minutes myself.

Not that I would not consider participating.
