Well here is the first bit of feedback.
Well done, and thank you so much for you effort. Most things have now been modded and a lot of the new modders seem to be following the same loop and recreating what other modders have already done. Fun for them, but it does not draw people who have already played the more established versions several times over already.
So its key to try and find something that has not been modded extensively before, and looks like you found something.
So I have to take my hat of to you for that. I have just downloaded it and was very excited to test it out.
I could not download from that site using my edge browser as it seemed unsupported, but switched back to IE and it downloaded fine.
First Mission: farm yard mission, and have to admit I was impressed.
As Xenonuats vanilla is definitely about creating extra suspense through the sound effects, your mod kind of needs to do the same to add that extra excitement.
Less is definitely more, as they say and I think your mod keeps the suspense nicely, its not flooded with extra sounds but just a few here and there.
I liked the sound of a fighter craft flying past in the distance at one stage, would be nice to hear the occasional air to air combat too, but you may have already done that.
My only constructive feedback I can think to offer, is any cute and cuddly sounds like spring chicks and lovely robins chirping will kill the atmosphere dead. When birds are scared, the don't sing mating, or happy songs, they just tend to chirp warnings.
Right cant wait to go try another exciting mission. Thanks so much for you effort in producing this.
I love it, and think you could really take this somewhere.
[EDIT]
The crickets in the night missions are epic, that is such a nice touch. Well done for that.
